Frost is fun and I'm aware for a lot of mages it is standard to play this spec each season. But why can we never play as fire or arcane? I don't play my mage in MOP since I dislike the way I am forced to play frost, hate having a pet and I'm not a huge fan of the level 90 talents (they feel like a restriction than a bonus) but that's another topic for another thread.
Other classes have more than 1 viable specs so why cant we have fire or arcane useful?
For those saying I'm talking nonsense here is 3v3 representation of specs. As you can see above 2.2k fire and arcane combined together have a 1.2% representation. Both of those together is less than HALF that of prot warriors.
