The talents system needs more choices imo, and the main issue is not balance at all the talents should be there for fun to be able to change things up with your prefered spec.
So long as there is one build that competes in the high end of the meters things are fine, and if ppl dont like a certain talent that is part of the best blizzard will usually change it so that a more liked option is viable.
The talent system is not an illusion of choice as many will argue, because it is choice and me and many many others have often performed well with non cookie cutter builds despite what theory crafters say is the best.
I was sad to see the old talents go no because i had much more choice for raids, there were always builds that were the best, but because you could make brokenly good hybrid builds for soloing and pvp.
