This isn't an exploit. You have a fate designed to kill tons of baddies while getting to a handful of other baddies. It boggles my mind why anyone would consider using an intended game mechanic of a fate to be an exploit. If it bugs you that much, run ahead and kill the mobs. Just like someone always does for turn-in fates that spawn infinite mobs. You get 3 minutes of XP, then someone loses interest and turns in their items and runs off. No big, move to the next fate.

I can tell you though that I look forward to having this available when I level through my next job. Because anything that can speed things along at that level is helpful. It's not like there are any quests right? (Especially on your second job)

I'll tell you what Badger, i'll trade all the fate grinds in the entire stinking game for better and more quests. I would love to be able to quest through a second job, or a third job if I decided. Boy would it be sweet to not have to fate grind to level though.
