I'll admit they could sure increase the sp for quest, but I perfer party grinding to solo questing. I left to play Rift and hated it because all you do is solo level on quest, I went from 1-36 doing that with out partying with another player and I quit because of it. In grind parties you are always playing with someone else and meeting new people, that's why XI community was great the way it was because you were almost forced to play together and not be antisocial lol. Hopefully they can add content that will make you happy but I don't think grind parties are a bad focus for now. Grinding on mobs in a party is what you do in any Final Fantasy.
