My favorite kind of tank..

If that tank survive the pull without heal ( because healer is drinking ) .. then yes that's my favorite kind of tank who doesn't need much healing.

If he take too much damage and I (healer) have to break drinking and start throwing emergency heals .. then that will be my least favorite kind of tank.

My buddy always try to find a single mob that the dps and he can beat on while the healer drinks. he lose 10% of his hp at most, he keep the dps entertained, and the healer can take his time. I'm not saying he is the best tank, but I like to think he is all right :)
