I'm sorry, but I think most of the talent trees are good with adding about 3-5 points. Getting to that next level does give us some OP stuff, but by that end of the game, I think we are ready for that craziness. Everyone right now makes some tough choices and I think we would be OP with 3-5 points now, but at level 90, we wouldn't need 3 new spells, that's for sure.

The thing about the current system that irks me is that you are finishing up Outland when you finally reach the bottom of the tree. A complete revamp means now we will be locked in until we finish up Wrath. While RaF is extended that far, one spec without flexibility because you are just trying to make it to the bottom before flexing your spec is tedious.

You don't put points where you want sometimes anyways as leveling has different requirements than endgame. Then some of those are completely OP for that level. I remember my SV hunter going up by 1kdps just because of a well placed talent after lagging behind the entire group for most of the dungeon.

Do these things need a real revamp? I don't think so. Nothing is balanced for leveling anyways. The benefits of a different tree are almost always just additional perks as they want. Another 3-5 points isn't going to break that (yet). Once the end level is above 90, then we can really talk a need to revamp how talents work.

Worst case scenario, I would still just use the same system but say you are locked into the tree for 35 points (though bottom is still 31). It would make people take a moment to place talents where they want instead of feeling like they have race to the bottom so they can move on.
