First of all, I will point out that I do understand why, from a balance and game mechanics perspective, no class can use every weapon. That being said, when you consider it from an RP angle, it begins to get a bit silly. Perhaps it's not fixable, but it is at least good for a (sometimes bitter) laugh.
So the orc warlock can handle the big sticks, the small pointy sticks, but combine the two and somehow, thar be probs. Sure, if this lock can hold it in one hand, then that's doable. But two? Tiny blood elf pallies can totally handle that monster, but there's something about warlockery that changes even the big orcs into weaklings.
Why can't my holy pally hold a dagger? Come on, I promise, she won't even use it; just leech all its stats. I guess pallies just aren't subtle. At all. Attempts to teach stabby stabby by the great gurus resulted in furrowed brows, a few injuries, and several panic attacks. They're going to stick with the elaborate swinging motions, thank ya. On that note, why can't she hold a staff? Pointy staff, no problem. But stickz = idk.
