When two tanks duel without dying... you know there is a problem

[Shurrikhan]

Easy solution, remove potions and add a skill as a dedicated heal and condi clear skill both on a 24 sec CD. Somthing like this just in pvp modes may work.

Or perhaps just have percentile mitigation also apply to effect duration? Voila, tanks don't spend their whole time getting CCed into oblivion.
