Back in 2009 when Cataclysm Dropped, every class had to pick a Spec, and then they were locked into and restricted to that one specific talent tree and ONLY that one tree until they spent 31 talent points in that tree, at which point they only had 10 talent points of which they were free to place in any tree of their choice.
OK, now that we are all up to speed, I’m going to get into it.
Cataclysm Classic has not been announced and we do not know if it is coming or if we are going to get some kind of as of yet undefined abstract “Classic Plus” which sounds as exciting as it does mysterious.
HOWEVER, if Cataclysm Classic is coming, the removal of the talent tree restriction upon selecting a spec would be a welcome change. It would allow new styles of gameplay, encourage people to theory-craft, and promote the open customization their toons in a way that they had not had the ability to do so previously in such an era.
