Beast gauge gone in dungeon

That makes sense, next time i'll remove that stone so my hotbar goes back to marauder

There’s no need to do that. MRD and WAR share the same skills sub-Level 30 where you’d actually start getting WAR-only skills, so removing your job stone won’t do anything beneficial for you. You also can’t do that once you enter a duty.
