Lockpick...
Having used it a lot in DD, I've learnt it early doors in BD as well - I think I've invested three skill points in it so far. I've never successfully picked a lock. Of course, in DD you needed lockpicks as well, but I'm halfway through Act 2 and not seen one yet so I was assuming that this was one of the things that had changed in BD (certainly hope so, I was carrying around a fair bit of weight of lockpicks in DD for those times when I needed them).
So, are there lockpicks and I've just not come across them yet. Or are there no doors in the early stages of the game that you can get through that they don't give you a key for. Or is it just a waste of skill points?
