just echoing what some have already said, jokes on them if they kicked you, you get insta queue, they? stuck waiting for tank.

Also, you will never satisfy anyone, you pull small you will annoy the "pull everything" crowds, if you pull big you will sometimes ended up with stressed healer who arent used to it.

In PUG situation/random duty if they dont ask me to pull big, my pull size will be gauged from my party kill speed of the first 2 pack of mobs that i pull and how healer can maintain my health.

I rarely see people giving tanks a hard time by pulling small though, except if the tanks gets partied with 3 premade douches, which in my experience, really really rare.
