Mage in PTR 3.1
Lot of things can change by the time they actually release patch 3.1. It certainly sounds like they are a long way in the PTR and doesn't even sound like they're down with Uldar.
So far we are having a hard time with a couple of changes. In case you haven't followed, we play a Mage. It makes sure that we have a few alts but we played on our Mage for outweighs probably all other toons combined. We imagine it will continue to be that way.
Above all, most of the players will be very excited about the dual spec thing. As a Mage, we could really care less. It makes sure that i ion kinaht sounds neat. We figured we could have a PvP spec for those rare times when we actually go PvP but it really wasn't a necessity. In fact we figured it would be more beneficial for our Priest when we need her to heal something. Per Armory, we've respec'ed twice. We'd have to respec 23 more times before it would have been cheaper to simply pay for the dual specs. We get to know that some people will be happy about it, and they'll be able to change more without having to worry about the money, but still Hunters, Warlocks, Rogues, Mages. Is it really that big of a deal for them?
