My Syrcus Tower party Vote Kicked a Ninja just today, for using his abilities to get to the arenas earlier than everyone else, and start a battle - locking out some of the Alliance members. By the time we got to Acheron, we'd all had enough, and no-one (including the other Alliances) refused to enter the Acheron arena until he, and another party member that was being equally annoying were Vote Kicked from my Party.
