Look, troll bot, in a fight against a hunter and a healer, take out the healer and then the hunter. Pretty simple. Killing a hunter is a slow process for a paladin and it's impossible to kill a hunter that is getting healed. I know you're a moron, I know you like to try and initiate pointless shit on the forums, but this is beyond your normal level of stupid. Is it even worth responding to you in future? Do me a favor and keep the moronic remarks to yourself.
As far as healers generally go though, druids are the fastest to kill. Paladin armor and mobile healing make them slow to kill. Priest bubble and fear takes a while too. Shamans can kite and their healing makes them almost unkillable. Druids are the fastest to kill, and I always take out the weakest first.
Only a fool ignores an easy target so they can concentrate on something you consider more worthwhile.
