Yes it was very abusable. I actually like that they have changed it so each item you steal is a separate roll with a separate difficulty. How much you want to press your luck is a fun minigame. But even DoS2s system of NPCs having heightened awareness and looking for someone to interrogate for a while is better than this.
Psionic knowledge that your group are the thieves even if you dont mess up the pickpocketing isnt very fun to interact with.
