Personal Experience

Grinded out 3 Elvia cups, now I have to remove them and place them onto the Kharazad Accessories. 
The accessories aren't as simple as buying enough for all 6 pieces (50 dawn essence each etc, roughly 10b a piece).

Finished my DAHN Gloves on my Mystic -> But LOML was done on my Striker.

Tagged Dosa, but every time I kill a Hong Lim BOSS he drops 700 trash loot and I am overweight.

Tried out HUNTING, only to find out I need to be a Striker (crit chance lol). People say just transfer gear over, but you need CRYSTAL SLOTS even with Lifeskilling.
Some of my classes SUCK in Tier 1 / Tier 2 (capped) content.

Quest line needs to be account-wide.

This way all characters get every single "free" inventory slot from the Black Spirit. The game just has too many items.

As a new player I started as a WARRIOR, then proceeded to try every single class. It gets annoying to even do awakening/succession quests.

Pearl items
Tagging has been reduced, we all know it's so players find a new class to play to "reroll" and spend pearls.
There is too much now, from Horse Flutes, WEIGHT, inventory slots, lifeskilling outfits, pay to win fishing.. etc.

With every new update I find it harder and harder to "recommend" BDO to others to enjoy. There are MANY new players I have seen enjoy the game in the beginning.. then swipe $100 to buy random stuff. Only to find out when they return to the game -> it is character bound.

With the state of Forest Furys and that cups on Kharazad are locked in, I dont see why they cant just make the extraction from old accessories for old cups removable at all times with a mirror like they did for the very very very short event window when they released the Cronazard accessories.
