In a way I do sympathize with the OP here, though I must say, I usually get more SP than that even when soloing leves. Not a ton, mind you, but I usually get at least 1600 per leve even on a crummy leve with no GA.

But leves are touted as being great for people who don't have a lot of time and want to log in and make some progress in the limited time that they do have. They are supposed to be good for soloing since finding a party -- even a small one -- takes time and/or luck. As it is though, the discrepancy in SP gains from being in a leve-link party vs. soloing your leves is really huge.

But mind you, I have terrible luck finding leve parties, so my opinion probably differs from those of you that are more successful in this.
