We really haven't ever supported the true hybrid builds where someone goes halfway down two trees. It would be one thing if someone really wanted to play say an Affliction warlock who also emphasized demons or the Ret paladin who also wanted to be a better healer. But almost without exception the hybrid builds that have ever existed involved sneaking down into a second tree to get an overpowered talent or two. The developers never really wanted the last talent in a tree to be a decision. They want you to get that talent. When players would make builds that didn't go to the bottom of their tree they would feel like something was wrong with the tree. Nobody wants that 31-point talent to be a hard choice.
So, yeah, go get that 31-point talent. You'll have some decisions to make on the way down and then you'll have 10 points that can get you 3 or 4 additional talents from a pool of 15 or so that are left over. Not all of those builds will make sense, but many of them will. That feels like plenty of choice to me and both you and we will know that you have the basics that make your spec work.
Any chance of someone mentioning this to the guy who is working on the Fury tree?
