People playing a DPS class tend to not pay attention to the hate meter in lower level dungeons in my experience as a healer and a tank. Even when they pull hate and the mob is bashing in their face they continue to do as much damage as possible, if it is close to death I can understand but most times it isn't even close. I tanked a low level dungeon with an archer who stated it was his second dungeon, he wouldn't even wait for me to finish marking all the targets. I would mark 1 and immediately he would hit it, and when you only have a few enmity skills and a DPS going nuts it gets annoying fast. Hate management isn't just a tanks job, everyone in the party has to manage it. People tend to blame the tank for not holding hate, when they are at fault for not managing their hate. More often then not DF groups lack synergy, it is every man for himself especially when it comes to DPS classes.
