That tank might not be a jerk, since MOST people want to skip the skipable. BUT, the play here, i beleive, would be this : tank needs to ask if all players wish to skip. If he doesn'T ask and just go... i would heal but i would ask to hold on once that pull is over with. THEN i would proceed to explain my opinion and ask the party if anyone needs any XP or items... REfusing to heal is assuming the tank is a jerk. So it's assuming wrong. BUT, a tank that doesn'T ask and skip is also assuming wrong.
