Maybe i whent oevr the top, but.
Please understand you are not entitled to decide how a dungeon run goes because the mobs hits you in the face, thats what you sayd, (thats the part that ticks me off most because it absolutly makes no sense). You are part of a 4 man group and not the othere way around, that 3 people are part of your dungeon run. In reality every DD and even a healer can tank a 3 enemy pack without problems in most cases. You are part of a party and not the party nor do you have special rights. Again in reality you could not do much without a healer at all. So please try to get the dungeon done smooth even if a other party member pulls a mob or does something else you dislike. and play as a group where everyone has equal rights and respnsibility.
