2. Somebody already told but when not using lockpicks you should have a chance to destroy item inside. I really dont know how this went unnoticed for the whole beta tests?
This is something I hate in many RPGs, the need to have a thief in the group or specific skills to open doors, chests and detect the traps. In DoS I can detect the traps thanks to the perception of my warrior and open the doors with fireballs without spending points in any thief specific skill and it's a good idea. I can play without thief and I like that. So I don't want to spend skill point just for safely open a chest but I admit this is a logical idea.
But I don't like when items can break randomly in RPG (like fail a craft or a weapon upgrade...) this is not fun and anyway many players will reload.
For me, difficulty must be in fight, not in random things.
