Your healers are terrible. Stop complaining that your tank class sucks, and learn to get healers that aren't afk, sleeping, beating off, stuffing their face, and have a generally good understanding of their own class.
If i missed any reasons why healers go afk, i apologize. There is a lot of reasons, because many healers in general play a healer to be lazy.
My healers don't suck and overall it's been a lot of fun to tank, like having to move and pay attention and stuff is fun - even if it's a bit stressful at times in certain encounters.
