I would just like to say it is funny to see people complain about a skill cause they get ***, yes Mistform is broken even though it only says you gain the invulnerability to healing magic when you cast Mistform which in my personal opinion is the only thing here that is broken I would just like to add that everytime someone complains about this skill it is only always been a emperor in PvP which is able to do this only because they are emperor and the point of being an emperor is to be hard to kill and take out a zerg.

Next I would like to say that more skills are hardly op, you only need to know what to do against them, a little tip on the vampire emperor they have to be close to lots of people in order to survive using mistform and batswarm reguardless of if they can spam it or not best thing to do is if you see the emperor back away keep your distance and spread the hell out nuke from a far even if they have a pull or charge skill they will run out of mana/stam just trying to get enough people close to them to use the Batswarm/Mistform combo thus making that said combo ineffective.

On a side note now that this ridiculous complaint has been explained a DK emperor can be just as hard to take down simply by also spamming his ultimate MagmaArmor or whatever morph they choose combined with the morphed form of Inhale(Drain essence) which would alllow them to take minimum damage while running around draining the hp from players in a large group(once again can be countered by spreading out).

Long story short please look into the game in depth before making stupid complaints because you get you butts kicked by someone who is suppose to kick your butt in the first place.
