Rogues in general get the short end of the stick with BG3.
Everyone can potion chug bonus action, thats a Thief class feature.
Everyone can use scrolls even when not having the spell on their spell list (example: Fighters using scrolls) Thats a 13th level class feature for Thief (!!!!!!!!!!!!!!!!!!!)
Second story work doesnt add distance to jump with Dex mod and climbing is not really a thing in this game so instead they get resistance to fall damage lolwat.
Bonus Action Hide is already mentioned here. So instead Thief's get 2 BA. Wut. That turns them into Dual Wielding death machines, coupled with the fact that EVERY character add Ability Modifiers to their off hand attacks (I'd say this is a bug since Two Weapon Fighting is a fighting style in the game that does nothing)
No Expertise is also already mentioned.
Crit success and Crit Fail on ability checks. In 5e these ONLY apply to attack rolls. This will likely interfere with Reliable Talent class feature, since 1's should be treated as 10's. But it could very well not.
Mage hand having its own turn in initiative. Mage hands require a turn to control and cant attack, so therefore cant shove. Also is not invisible. ONLY Arcane Tricksters mage hand is invisible, and uses a BA to control. Its not free. Still cant attack or shove tho. Also sneaking mage hands???? wut.
