If a master chooses not to lead his element in war, that is acceptable.

If that master joins another element, they are a disgrace to the element they are master of.
Though I do feel that, whether or not they join war, they should make people know that that is their element. Make them take into consideration that they will use that deck, regardless of the meta. That is what makes a master.
