Couple items from my short time

I literally got into the beta 1 day before it closed so apologise if this is known.
I purchased some health potions from the shop and notice they will not slot in the health potion open bar, but will in normal action bars, they were the ones that gave 600hp immediately, not in game now obviously so I cant tell you the name.
Secondly I mis clicked and got to a card game? it seems its still all in Korean, words and video to show the game.
Other than that my game was relatively smooth for the 4 hours I got to play, I would consider an exclusion zone or an outline around relevant quest givers so they do not get lost in the crowd for busy NPC’s.
Also the bard songs, its not obviously clear you need to click to add them before dragging to the action bars.
