I think nerfs are good. In PvP at least. The TTK should be slower. Remember how fun the first few weeks of crucible were? That's the TTK we should have. It's much funner when there's more skill and more time to react involved. As for PvE, the ghorn was completely OP, trivializing nearly all encounters. I do think the icebreaker and black hammer nerfs were uncalled for though.
