Third, if you are at a big ice while everyone is wailing on it, the worst thing you can do is ignore it and try to take down players. This often ends up with your team missing out on 100-200 points from ice, and not getting anywhere near the same amount in kills. If that teams healers can delay the attacking team long enough, its a huge loss for the attackers. And healers in general if they are smart ignore direct dpsing the ice to watch for people trying to do that, since all dpsing as a healer does is drain your MP quickly for little relative benefit. It was the same in seal rock, when the node was low enough you didn't stay to kill people, you disengaged to be ready for next node. A lot of times people lost the game not turning their back on a team and slugging it out, giving the third team the ability to cap nodes and get a lot of passive points while the other side stayed the same.

I kind of wonder who you are fighting that you can so easily win via kills.
