Give back the Stun on on the 'Hexeblood Sundering Roar' and remove the Knockdown. Currently, the skill overlaps in function with Extinction as both are Knockdown. As a followup Knockdown 'Dragonblood- Crackling Flame' is readily available.

Give back the KD on 'Hexeblood Tip of scale'. This change made the related core worthless.

Change the stun on 'Dragonblood Storm Piercer' to be PvE only and make it Frontal Guard. The skill is too slow to be used as a stun. 

Similarly the Aerial Burst ability having a stun is pointless. Make the Stun PvE only and turn it into an SA. 

Replace the 'Core: Spiteful Soul' with an 'Core: Obliterate' that grants Knockdown or Bound.  

Aerial Burst having CC is good, just need SA on it.

Adding Old Storm Piecer's damage into new DB: Aerial Burst is good.
Need the legacy's Shift+E keybind back.

Removing RMB keybind from DB+HB spiteful soul would be a good option as it already have Shit+RMB keybind.

Giving RMB keybind on the Extinction is good.

Giving back Shift+F keybing to Flow:Oblierate is good.
Removing Float CC from HB: Tectonic Slam and Storm Maul is good then give them SA & iframe into lingering SA.

Giving DB: Tip of the Scale a FG is good.

Giving SA on Flow: Cloud's Strife is must.

Giving Knockback effect on DB:Tectonic Slam is good.

Remove Grab and make Dragon Blood kit to be 30% faster attack speed.

"Replace the 'Core: Spiteful Soul' with an 'Core: Obliterate' that grants Knockdown or Bound."

Maybe instead of Core: Obliterate; Core: Doombringer with float in it would be better.

"Aerial Burst having CC is good, just need SA on it." -- Awakening skills do not have a protected CC unless you get a Core for it.

"Adding Old Storm Piecer's damage into new DB: Aerial Burst is good." -  The new Aerial burst in Dragonform is a PvE skill.
"Need the legacy's Shift+E keybind back." -- Would be very nice.

"Removing RMB keybind from DB+HB spiteful soul would be a good option as it already have Shit+RMB keybind." -- No comment.

G"iving RMB keybind on the Extinction is good." -- It was simply Hotkey or F before.

"Giving back Shift+F keybing to Flow:Oblierate is good." -- I agree
"Removing Float CC from HB: Tectonic Slam and Storm Maul is good then give them SA & iframe into lingering SA." -- I completely disagree these are the main skills to engage or counter grab attempts. Also one of the best ways to counter FG on the class. With the high mobility on the class having at least some movement gaps is good.

"Giving DB: Tip of the Scale a FG is good." -- Then the CC must be removed. 

"Giving SA on Flow: Cloud's Strife is must."-- I also don't know why it doesn't have it. Perhaps they believe the damage is high?

"Giving Knockback effect on DB:Tectonic Slam is good." -- Then the Protection must be removed. 

"Remove Grab and make Dragon Blood kit to be 30% faster attack speed." -- Perhaps that would make the class more balanced with how the Dragonwalk - Grab is. Overall that would be a large nerf however and at this point you might as well play musa, woosa, sage or maegu instead. 

"Replace the 'Core: Spiteful Soul' with an 'Core: Obliterate' that grants Knockdown or Bound."

"Maybe instead of Core: Obliterate; Core: Doombringer with float in it would be better. " -- None of the Dragon skills have a core.

Mate drak barely has any protected CC and her dragon blood kit's attack speed is super slow. She has no lingering protections and must be on constant move to stay protected cause her block is clunky af and can easily be CCed through it or get grabbed.

And now her awak kit has very less protections and her CCs are messed up (from my pov).

ofc dualing against non grab class is no problem as i can just dish out dmg no regards of being CCed much if i don't focus on CCing them but other 90% of classes have grabs and much more protections. Ninja, kuno, valk, warrior, guardian, DK, hash, Woosa, Striker, Mystic, Ranger, Berserker..... so on.

I don't wanna cry begging for ccs and protections but having protections and ccs on right skills is needed.

We don't need CC on HB: Tectonic slam and Storm Maul as they are mobility skill with very small hitbox.

Storm Maul was better pre-release of drak on live server, Iframe into SA(full animation, no CC).

her dragon blood kit's attack speed is super slow -- This is why it is 99% protected and outdamages most classes in the game. 

She has no lingering protections and must be on constant move to stay protected cause her block is clunky af -- This class has more mobility than most others in the game. That shouldn't be an issue. 

awak kit has very less protections and her CCs are messed up -- This class can easily stay fully protected. As with many other new awakening classes the difference between the preawakening and awakening causes the "lack" of ccs. In this case the available ones are completely fine if not stronger than on others. The Core (protected cc attempt), hTS (to counter FG), Stormmaul(to counte grabs) and one of the strongest grabs in the game due to the cancel from refraction, Crackling flame (Very shortly unprotected KD due to legacy), ToS if you like those, . I personally don't have your issue.

Lastly. Awakening skills may not have protected CCs unless given by a Core. This is simply a rule of the game.  

Imo Drak is in a relatively good spot right now. Not overpowered but not bad either. She has good mobility, good protection and decent ccs. The grab is a bit clunky to use but it's okay.

There are only very few things I'd like to see changed right now:

Give us either SA, FG or at least a Downsmash on HB: Crackling Flame. No other class that I know of has awakening skills that have neither a cc nor any protection or mobility or at least a downsmash. It's a nice filler skill imo but without anything on it itt's rather worthless.

Remove CC from HB: Tip of the Scale and add SA to it. This skill is very long without any protection. The stiffness on it is also useless.

Add SA to Flow: Cloud's Strife: Why does the flow not have SA, but has neither a CC or can be used without Spiteful Soul/Tip of the Scale. Due to it being RMB, it keeps fucking you up when you want to not use the flow and rather use your sideways iframe.

Give us more ways to switch automatically from preawakening to awakening:
We can already use the Rabam skills or a few other skills from skillbar as a swap to pre-awa, but there is, to my knowledge, only Doombringer from skillbar to swap back to awakening. Let us use Aerial Burst (we have to hotbar it anyways) to swap to awakening and also let the grab automatically swap to awakening when preawakening abyssal fang is locked (some other classes can do things like that).

Her movement speeds are very fast and i understand that. She is almost as fast as ninja in movements but the question comes while attacking. her skill activation is slow and it can't be cancel fast with dragonwalk either, you are basically stuck there for a few ms in an animation lock state and can easily get CCed or grabbed.

Ofc her dmg is high and it must be that way cause by the time she fully cast her skills, other classes can use 2 - 4 skills already. don't look at one button press dmg.

This days almost all classes can stay full protected and while fully protected, they have enough time to use unprotected skills for hard CCs and be protected again and very fast. Not to mention striker who has 11 protected CCs and fighting striker (good strikers) is like trying to win a 1/1000 odds. I don't wanna mention ninja, this class is becomming more and more protected and the only AOE CC now i use is the new DB: Arial Burst (in hopes of catching him).

and finally, I have 0 problem with her when i fight against player who don't know what they are doing. it all comes to DMG vs wtf attacks.

If i have a hard cap gear with human dmg crystals then i can melt everything while they user FG or SA but skill vs skill; i sware ma balls be sweating, sheesh!. Keeps reminding me how OP old classes mechanics are when used properly.

Warrior be scary as hell when i know what they know they are doing and all the other sus classes beside Shai, Musa, Maewha, Corsair, witchard.
