Just remember, you're the tank. The only one you have to fear p***ing off is the healer. They aren't replaced fast.

If a DPS wants to go faster than you, let them. Let them until they learn. Your pulls should be received as a statement about how much you can manage before risks come into play. They simply can't pull AND justify anger if you're alraedy fighting 3-4 enemies and they go ahead and pull more. Often times the same people that do this haven't gauged how much you can take (sometimes it's never-tanks and sometimes it's people that can only remember tanking over-geared) and nobody elected them to do so.

If the whole party thinks you're going too slow. Maybe you are. Though, i's not entirely impossible to roll for 3 extreme inconsiderate players but in my experience it feels like a 20% chance that only one will be and a dramatically lower chance that there would be more. In any case, if they can muster enough votes to kick a tank, they can have fun waiting for another while you will be with your new best friends is less than a minute.

If you've done it before, absolutely make attempts to go quicker. Many fights don't really need learning and you can just stick to your golden rules about timing stuns, facing the mob away and saving protective oGCDs for the most intense moments. Everyone should respect a first time claim though. People who don't give themselves too much credit for being a decent player, let alone a team-player.
