I'm a big puller. I pull wall-to-wall unless my healer asks for me to slow down (to which I WILL). I also wait for everyone to be out of cutscenes before I start attacking the boss - regardless of whether or not one person has pulled. It doesn't matter my role in the party, whether I'm tank, healer, or DPS. I don't do so to feel superior to anyone, to shove politeness down peoples throats, what have you. I just feel it is only fair and polite to allow everyone the same luxury I had - to watch cutscenes without feeling pressured. It doesn't matter if the cutscene is just 10 seconds of the boss jumping into the arena. When someone's new, they don't know that for certain - especially considering the game likes to throw oddball dungeons where the cutscene IS important to the plot/drives the plot forward in some way shape or form.
