I can understand when a new tank complains, but I've seen healers and dps complain too, even if there's an experienced tank leading the way. Why? All speed runs do is speed up the run, cutting out the extra crap that doesn't need to be done. Is there a reason why people absolutely MUST fight every last piece of trash in a dungeon? I know some say "I don't know how to do it!" so here's a guide in speed runs:

1: Tank runs to boss room (or safe spot if they can't make it the whole way)
2: dps/healer follow tank
3: tank dies away from the group

Sure is hard isn't it? But people refuse to even try it, and that's just sad.
