The case has already been made and it's incredibly simple. Death Bloom could be completely removed and raid necros wouldn't feel it because of all the mana synergy on raids. Or DB could be given a 1 minute recast for that matter and a raid necro's mana situation wouldn't change nor would their dps increase. DB is essentially meaningless on raids except as a way to return mana after a death. Groupers on the other hand rely on and were tuned around a 3 minute Death Bloom to be relevant in the group game. So instead of giving groupers an OOC requirement punishment (which no other class has to deal with for their mana return abilities) just so the devs can continue down this ineffective raid necro nerf crusade they could just roll everything back. Groupers wouldn't get unnecessarily nerfed and raiders would still be in the same position they've been in all along (due to raid synergy, not DB). This should happen but is guaranteed to not.
