They dont need to do all that, just make rogues even remotely close to good dps. I think that would be a start.
Unlocking doors is a cool trick for a few scenarios. Getting keys in Unrest though, never seemed to be a problem for me though. But pick lock does not make or break the class. Rogues are dps and the class thrives or suffers based upon its perceived dps. Right now it is perceived to suck.
The very first time I skilled up lock picking on a rogue I actually sat there for hours and hours clicking the mouse button myself.
