Welcome to Ask a Lore Nerd, where each week Alex Ziebart answers your quests about the lore in the World of Warcraft. If you have any questions, no matter how big or small they might be, ask them in the comments section below and we'll try to answer it in a future edition.
We'll start off with Cole's write-in question...
Why can Rogues use Maces but not Axes? What's so sneaky about hammers but not about edged blades of death?
Well, this is likely more game mechanics than anything. They need to split up which weapons can be used by what classes evenly, or you get a severe loot imbalance. If you want to justify it in-character, maces are really, really good at stopping your opponent, rendering them unable to fight back, or fight ever again. A cut leaves a scar, a shattered bone leaves a cripple.
The Mace Spec that everyone hated so much in PvP? That's pretty much how it goes with maces in real life. You thonk someone on the head, and they're out of it. I could see a Rogue playing dirty like that. Coming up from behind, cracking someone over the head, then swinging low and shattering the next guy's kneecap.
Why can't they use axes? Probably no compelling reason besides game balance, though I'm sure they would be harder to use in a Rogue-y fashion than swords, daggers or hammers. Axes are probably the most unforgiving of all of the bladed weapons. You want a hard swing, not so much an elegant stroke, a well-placed shiv, or a busted joint. Axes tend to be more about being heavy and using momentum to cut, rather than sharp edges. Not always, but that's their tendency. Maybe they weren't graceful enough to make the cut*? Who knows.
Why did they retcon the Draenei lore from WCIII to WoW BC? What was wrong with the original lore (ugly, thin, primitive Draenei).
