I dont think its fair to take away ice arrow. is it annoying - yes but so is so many other skills and buffs. I had a look at your gear and i see you dont use Ice accessories, probably no ice resistance in ML skill tree ether. that makes a huge difference bro. Soul barrier and dmg cap i think is fine as it is.
Shuryk, this is a bug... wrap it in what u want it will still be one. No one should be immune to damage on a PVP event. Will u say using a duel so no one can kill u is not abusing a bug also? In a PVP Kundun event the one who does most damage wins, but the ppl who get killed lose their dps done to the boss. This way he was able to hold his dmg done all trough the pvp kundun and take the kill.
