When playing a Healer I would vote for the Tank, unless he kept allowing me to be mobbed, or worse yet have a bad personality. If that happened I would choose the DPS who used the most energy...not mine, his own. When playing a DPS I would always vote for in this order; Healer if they did good, Tank if they did good...but everyone is always in such a hurry often times who ever hasn't left yet. lol But now that I'm learning to tank, I vote for healer as a professional courtesy....if they are still there, then I vote for who is left.

....why is everyone in such a hurry??

After we finish my toon spins around like that Miqo'te did after Hildibrant's father ran after him, when they hurry for the exit, as if they had seconds to live. lol "I don't bite...but I can't speak for that creepy Dark Knight over there." O.O
