How many dks actually double grip the same target? Generally you want to grip your target and another annoying ranged so you can spread diseases or interrupt casts or get them out of position. Only time I grip same target is a mage when I know hes going to blink and dark sim is down or something. Thats really the issue with it, hell dks hardly need uptime anyway considering over half their abilities are ranged. Spec deaths advance, unless your rooted you are literally unkitable.
