Just to note, you can and will get vote dismissed if you keep trying, since you'll be wasting everybody's time. And trust me, rather than spend all that time waiting for the tank to get a brain, the healer or DPS, whose times are being wasted, may just start a vote kick which you will probably lose, especially in prime time. Remember, to anybody who has an FC with 4-5 tanks, the current bad tank is easily replaceable. And to the DPS who don't, they may kick you just to leave so they can party up with a healer to avoid the queue time.
