Personally, I'd have to agree with the OP that FATE zerging is not my ideal way to level and I doubt that SE intended the player base to travel like locusts from fate to fate. Fortunately SE has implemented myriad alternatives to character advancement (quests, leves, dungeons, grinding, etc.) You can't argue with efficiency though, and I'll take FATE zerging over the 1.0 system where xp/sp was rewarded based upon battle performance. But I was pretty damn good at heal sniping :-)

I'd imagine there will be some balancing down the road of xp rewards derived from various activities so that xp reward v. time spent ratio isn't so slanted in favor of one definitive way to level your character. In the meantime though, I'd strongly recommend that everyone get on the fate zerg gravy train while it lasts.
