If you can super tank and not die then fair game yeah? Gotta use "hallowed ground" types skills more often. You can use it at least twice in a dungeon if you manage it properly. The tank has to good to begin with plus paladins are kinda op now, just heal yourself if the healer cant heals you fast enough.

Knowing the fights, CD management and geared makes super pulling easier. If the tank doesn't do it, then he is at the fault not the healer (unless the healer just spams dps and not heal obviously)
