tbh and i know this sound bad...but i typically ignored the "kill the healer" remark in pvp, unless said healer is near death. why? simply because the healer isnt the only main threat on the field. i cant tell you how many times i seen players ignore the smn, blm or brd cuz it isnt the healer. if the healer is crap, then sure kill him/her first;however, it just in my experience, any smart healer will just bait you to attack him/her all while their team smash your face in.
