there is a difference because when you do quests as champions or do raid bosses or dungeons it is assumed there is more than you alone, in a group, its heroes, champions, never hero or champion alone
you just become the leader of your class, they had 12, at least 12 champions, besides you were just being directed to something, you were not rly leader of shit, you had no power beside some war table nonsense, and sending some soldiers there, you could do nothing relevant, no power of choice i hate it.
faction leader is even more nonsense
