Well, Tanks no longer gain vengeance from attacks from Qiang. They 'gain' it, but it doesn't actually effect them.
This means tanks are doing drastically less DPS, literally 10% of the original dps our tanks were doing.
It also means drastically less active mitigation, my shield barrier for example now absorbs a pitiful amount of damage, whereas before it could get up to 400k+
EDIT: It's not just Spirit Kings.
Official confirmation from Ghostcrawler - across the board vengeance nerf.
