Another annoyance: we get less and less things to use our lockpick.
Don’t let us search for keys, just let us open cages and have a bit of consistency. Doors, chests, cages,… please more immersion for my Rogue!
As for pick-pocketing, doesn’t even have to be quests for me (would be nice though), just have quirky loot, add some every expansion but feel free to recycle the old stuff. If they feel extra fancy: items that give you a small amount of bonus rep.
Too many systems, mechanics and objectives get tossed away. Some more evergreen/consistency is highly needed.
