Right.
So Heavy Metal could possibly fit the WoW aesthetic, if it's done in moderation like a single ability.
If you weren't being such a hard-ass about it, we could have concluded this pages ago since we've been literally circling the topic for days just to reach this one point. You can go back to the beginning of the conversation and you'll see this is singular point we've been making for Heavy Metal fitting into the WoW aesthetic, as long as Blizzard is willing integrate Heavy Metal references directly into the lore. It already exists in the game, just not canonically through any class mechanics.
