Yeah. Replaying again, and proficiencies don't work at all. Equipped a shield with a battleaxe to my druid, it says she isn't proficient in the battleaxe, but she gets +4 to hit. Equipped a battleaxe to my sorcerer. Same result. Even though they aren't proficient, they can wield anything they want without penalty.
Just wanted to bring this back to light in case it might be forgotten by the devs. It's really important to the game to fix this issue.
And PLEASE don't forget scrolls. They can't be cast by everyone. Each spell has its own classes that it is listed under. ONLY if your class has that spell can you cast it using a scroll. This is just as important to the game as proficiency.
I'm REALLY hoping you guys are working on this kind of stuff. Not sure why you haven't fixed it for EA, but if it's at least in full release...
