Stun locking is a royal pain but there are steps you or your teammates specifically can take to lessen it's impact. Largest issue i have atm would be taking a single hit butcher block for 33% of my hit points from MRD while wearing 262 morale or BLM keeping your healer/team out the game for 51 seconds straight, 60 seconds after you burn purify. While there are 1 or 2 pvp skills you can counter each with the cd on them makes it a 1 time thing. I will agree that at least the BLM sleep takes some sort of skill to get off, the MRD situation takes 0 skill. With mechanics that reset your every cast by simply being sneezed on, being 1 hit for 33% hp is far too broken especially considering coming from a tank role while you have that amount of morale
