When you add up all these "fotm comps" including RMP, all wizard cleaves, and all double healer warriors, you have a large number of classes that are viable for arena. Aside from say, fire mages or fury warriors, almost every spec/class can fit into its own niche "fotm" team setup. Just as you wouldn't run into a 25man raid without a tank, or a hardmode encounter without an essential buffer class (shaman for bloodlust/heroism), you're not going to run into arena with 3x fury warriors on a 3v3 team to win against top teams.Originally Posted by Museigen
People can call them fotm comps, but when you look at it as a whole, just about every spec/class can be a "fotm" class.
(Plus, it's not really difficult to respec/dualspec. In my raiding guild, I raided as enhance, then dual specced to restoration/elemental to arena. Even then, even enhance is viable in "fotm" comps such as beastcleave)
