In DoS2 you can also teleport yourself to another statue waypoint, you do not even have to use magic pockets to avoid being caught.
Besides the way you can exploit pickpocketing in Dos2 the rogue mechanics were cool: the NPCs could see you, they know if you are being robbed, you have a weight and prize limit in the items you rob, you can only pickpocket one NPC and they try to find you if you rob them, but you can try to convince them.
I preferred the way they handled it in the Beta, where the robbed NPC called his friends and they seek you as a mob.
I do not know if you can teleport in BG3 but if you cannot and you can avoid that exploit you will fix a lot of things.
It would be cool if you can poison the food or put bombs in someone else´s pockets to use pickpocketing in a mean way.
Also, I would like to see a way to put stolen items in someone else´s pocket so you can frame them for your misdeeds.
I liked that in the TES games like oblivion the merchants recognize stolen items so you can only sell them to a fence, so the thieves guild get a cut.
