Meh.

I main tank on my alt(which I also raid on). At the start of every dungeon I ask "Big or small pulls? If no one replies I'll do what I think's best." And MOST of the time no one says a thing, so I'll speed run if every looks half-decently geared. I never get mad if we wipe, I just pull small the next time.

Not going to assume everyone's bad and pull small just because a healer is too lazy to type, "small" on a soft keyboard.
