Sadly we're the forgotten awakening sister </3
I think removing the Knockdown on Netherstrike in exchange for the skill becoming SA was such a dumb change and it just once again shows how out of touch the devs are with their own classes. 

Clearly making Netherstrike SA was a way for them to tackle the complains of ''No good n safe way to swap from pre-awk to awk''  but it was the WRONG stance swap skill!
Removing the Knockdown on Netherstrike made it so you can no longer reliably re-cc your target in AWK stance, we are litterally being forced  to swap to pre-awk to re-cc a target and try to kill them with our pre-awk skills and I think that's just so lame, it should be an option to re-cc someone in pre-awk stance it shouldn't be mandatory. 
We should be able to do a full reliable combo with re-ccs in awakening stance only, if we choose to do so, it should be up to the player what combo they execute and not something forced down your throat by the devs.

Playing an awk class in PvP and dipping into pre-awk skills used to be a showcase of class knowledge and knowing different combos and knowing what both specs their skills do, now as an AWK Woosa you only have 1 reliable combo and it involves 40% awk skills and 60% pre-awake skills and there is no way around it, it's no longer a show case of class knowledge or skill, it's something forced by the devs. 

My suggestion:
Remove SA on Netherstrike and give it back it's knockback, add a FG to Soul cleanse so theres still a protected way to stance swap from pre-awk to awk. 
Bring back fully Awakening combos!!
Thank you for coming to my TED talk <3

PS. Give awk Woosa the same love you gave Awk Maegu, if awk Maegu can be saved from the gutter in PvP so can awk Woosa. 

Yeah I was impressed watching the streamer Jaykun playing it in AOS. Looked rad. But for all the effort he was putting in, I don't think the class/spec did him justice. Succ Woosa is also way worse in comparison to what it used to be from what I noticed. Overall, Maegu's just way stronger. Both specs, not just in AOS, 1v1s but also in GL. Not saying they should nerf it or anything but considering that they're twins, it makes no sense for one to be way stronger than the other. 

Awake meagu never got changed drastically, class was the same people who were playing at it was so bad at the game they couldn't even make her work till a real player like reespo pick it up and teach the player base how to play the class then we got to see how broken class it is. I still believe awake woosa is the same we just need a proper player to decide to main and show to the rest 

It just seems like you do not know what ur talking about, theres alot of decent Awk Woosa mains in EU that do PvP etc.
The point still stands that Awk woosa is being forced to swap to pre-awk to re-cc reliably.
Awk Maegu never got huge changes but the changes and buffs she got were very impactfull where as the ''buffs'' Awk Woosa got were lowkey nerfs. I am not asking for big changes or big buffs but I am pretty sure we can all agree that ANY awakening stance class should be able to reliably re-cc and do a full combo IN awakening stance.
It makes NO sense that Awk woosa her hardest hitting skill in PvP is a pre-awakening skill and it makes no sense that if you want to reliably re-cc a target you have to swap to pre-awakening. 

I have to actually disagree here. If we talk about Awk Woosa in her current state, then the SA on Netherstrike is actually better imo. 

Our class can't SA trade face-to-face good, so we have to use movement to get into better positions and SA on Netherstrike allows us to go Netherstrike into Perilous Waltz (F into S+F).

All in all, if PA decides that we get damage buffs and are now able to damage trade, KD on Netherstrike would make more sense.

Also all of our skills have relativ low CD, so there is a high posibility that after your catch you either have Nether Blast or (Soul cleanse  into) Flow: River's End avaiable. If you really don't want to use Inkstroke as a third re CC, all you have to do is to simply not use Flow: River's End directly before/after Nether Blast. And maybe you have Blooming Death of CD, if both of them are on CD.

Here 2 combos without Netherstrike as KD:

1. Blooming Death (catch)> Bloom Deluge > Bloomburst > Nether Blast > ... (it's situational here, but most of the time you go: )

1a. Flow: Soul Shock > Soul Shower (cancel) > Inkstroke > shift+f > shift+e (now if you got both downsmashes from Flow: Soul Shock and shift+e you can try to CC reset) 

1b. Soul Shower > Flow: Soul Shock > Netherstrike > Perilous Waltz > Mark of the Moon (cancel)

In both combos you can use Soul Shower either before Nether Blast or after, depending on situation. Either way, you probably want to cancel it at the right time get the rest of your combo out.

2. Nether Blast (catch) > Life Lure > Bloom Deluge > Bloomburst > Soul Cleanse > Flow: River's End > Soul Shower > Flow: Soul Shock (> Netherstrike > Perilous Waltz, for some extra damage after the combo)

IMO what woosa needs is the Absolute: Stormfall Stun back, then either Sahee's Descent or Mark of the Moon + Flow: Death's Proclamation is turned into a burst damage FG skill and Flowers should explode faster if they are near enemies (like Flow: Seocheon Field).
