you dont have to wait, but if I am tanking, dont expect me to save your bacon if you over pull and get in over your head. If I am on a healer, I will be perfectly fine letting you go suicide. Many times pulling helps mitigate awkward rooms, helps maximize aoe attacks and helps blasters not faceplant when they use their damage to the fullest. If you run in front and cause a team wipe because you forgot your add meds, you arent being a team player anyway, so why would a team support you? If I am on a debuffer or buffer, and I keep pulling agro because the tank/brute wont taunt? I stop buffing/debuffing and stick to dps.
