I have no issue at all with helping people learn fights. I'm not a fan of speed running everything and I state this when I'm healing so the tank knows. I just see no point in stressing everyone out just to shave a few seconds off a run. It's always more fun for me if it's a nice run where no one's blaming someone else for not playing like they want them to. I would much rather help someone new learn the ropes than try to push everyone as fast or faster than they can handle then get upset if it doesn't work out.
