When I queue up as a DPS I tend to quickly check how much HP the healer has. You can tell by that how he or she is geared. Lower geared I go slower, good geared I usually start with 2 packs. If the healer isn't breaking a sweat I can pull alittle more. If the healer has bigger issues I slow down. Never did I have any complaint about my pull speed.

If a healer asks if I want to go ham on it all, then I will do so. Had that question a few select times.
