If I was one of those "only in it to win" type people, then, the way the game awards favor/victory points currently, it would be FAR better of me to just spec/spend Sedna to help me/myself/Sedna. Only heal myself, get lots of pouce and yetis and minions to kill stuff. Healing wind or healing other teammates, HAH, no way.
But I want to help the team, so I spec and spend to that end. But I'll never play Parth with her, cause you'r doomed to "Partisipant".
