Thanks a lot, at least someone sees my point without dragging everything to "but my dps went up" and "diseaseless blood ftw". Blood = DS, Frost = OB, Unholy = SS - this effectively means we got 3 similar abilities which have very little difference now.
Back then, we could choose. Now we are given standart 2-buttons rotations, and some base abilities are rendered useless outside their respective specs. Annihilation for OB isn't a tactical bonus like it should be - it's mandatory, otherwise the skill is trash. Same goes for DS - it isn't a situational healing tool anymore, it's just another spammable OB with plain damage for blood only.
