The spoiler dev comment all but agreed that the concession of giving necro the buff to all class skills, rather than just grave lord skills was essentially worthless. It's already been pointed out that the buff doesn't buff graverobber or animate blastbones. The only non grave lord skills being buffed are scythe and goliath.
This is NOT worth a 5% nerf in damage.
What I really want is stalking back, but since you're keen on murdering it into extinction, I want that full 20% back to get me to even contemplate slotting this skill.
