I have to say you are right on. DPS and heals just want fast runs and they need to slow down. Threat is not given and it takes a few seconds to build. The way I solved this problem is working with the healers and if someone pulls off of me I will not taunt back if it continues to happen. If they die, then they die! They will learn to let you do your job! It helps when you run with at least a guildie who is healing your runs. I believe as time goes on everyone will settle into how they play and will take more ques from the tank and the healers. We just need to have the experience players help the newer players learn. I feel better now knowing I am not the only one who noticed this problem and am very happy it is not faceroll tanking!
