Yea I am gonna mention guard, if you guard when a drk runs in, you don't get pulled and you don't take a ton of drg followup damage, if war just jumped you, you can guard and prevent getting blota'd, which most likely is gonna come out soon after, guard IS a counter to those.

And it's only 30s cd so it's up when next they try it again, it's as good a counter as purify is to a stun.
