Um...locks?!?!?! Maybe I've been playing wrong, but I've always let tools be applied to most/all locks, but relatively few traps.
In fact, upthread I thought I was being funny allowing Thieves' Tools proficiency to be used to "disarm" a poisoned doorknob, and since nobody commented I thought nobody noticed. But maybe you didn't see anything wrong with it?
I was referring to the sentiment that it's not fair to not let people "roll skills" whenever they want to, after they had "invested" in them. Since the only thing you can spend those points on is skills, if I treat all skills the same way then nobody can make a "bad investment".
LOL, true. Long day. I guess I also had the impression that you would find locked doors boring too.
