This list of what I think is poorly designed menus/UI/game. Sure alot of this is old but still stands to be annoying today. Alot of this content should of been tweeked long ago to be much user friendly.

Slip page items... why do we need them...? Never needed it when I had to store AF or Seasonal Event gear. Why not just talk to npc and choose the gear we want back...

Salvage armor Storage
Can only set 1 armor set...
Really... Let us store all sets.

Meeble Burrows
Why retrade pages...?
Even getting the page is useless. Should just walk up and choose the objective and it should save everytime we complete it and reset after a boss.

AF Storage
Really.. need to trade a full set and 1 of my pieces is +1 or I want my thf shoes only and not the other 4 pieces.

Limbus
White/Red Card.... really whats the point its right there as we zone in.
Maybe they just want us to run back toget the keyitem if someone forgets.

I'm sure there's way more... there's so much of it that there's way they go and fix it. Still why did they do such a bad job in the first place... and continuing to do so.
