Meh. After chasing fates for a couple weeks now, I've come to a few conclusions about what needs to be adjusted.

1- Spawn rates - They spawn too fast and too many. Slow them down a bit and adjust it so that there is only 1 fate up at a time. Maybe spawning every 10-15 minutes.
2- XP Awards - SOME of the FATEs need their XP lowered and some need it raised. Most XP awards are reasonable.
3- Monetary Awards - Needs to be raised quite a bit. Say, 2x for bronze, 5x for Silver and 10x for gold. Based on current awards.
