looking at the talent trees i am terrified that DF is going to be a crumbling disaster. blizzard took the wrong road with this. players should NOT have to spec into mandatory abilities for each scenario. every class needs all of their baseline abilities. if blizzard was to do this the right way they would make talents enhance these abilities and not grant them.
no class should have to spec into an interrupt. no class should have to spec into a class wide ability. and so on. this just makes everything flavorless.
blizzards bad decision snowball is getting massive as it is still falling down this hill.
