I have a problem with the tanks pulling literally non stop till the end of the dungeon, putting me the healer at the edge of my seat to not stay behind. I don't have a problem with fast tanks, I enjoy them. What I dislike is faster than fast. They don't even give me time to loot quest items. Yes it is leveling dungeons. I usually have to lay on hands them to save them, and 1-2 times even that wasn't enough to save the day. It is very stressful to me who is a 11 year player. I can't imagine how horrifying it would be to a relative new player.
For those who will say "communicate" and ask them to pull slightly slower, communication rarely happens according to my experience. If I step back to type "slow down" he is literally dead. I am afraid of being victimized by douchebags and get kicked from the dungeon.
I remember the times when I was tanking, I was looking to simple things like not LOS my healer, and give him some time to breath!
What's up with all this craziness and the speed races in non mattering leveling dungeons?
