Thievery no longer becomes that useful after half of Act 2 anyway. Magic charm actually generate way more loots at a faster pace for the players to update their gears with. Once you reach level 5, you always get the high tier gears about every 10-15 minutes. Imagine what it's like with level 7 or 8 Magic charm at all time.

With barter included, stealing becomes really unnecessary since you can sell old gear when updating it to reduce the cost. With how strong Magic charm is now with keeping player updated until a certain level, Thievery ends up being used for lock picking instead after mid act 2 because you keep having so many gears to sell and getting updated gears from chest. The gold will always go up as you play if you have Magic charm up so if Thievery is OP, Magic charm is borderline broke.
