I'm sure that Blizzard didn't intend odd behavior to mean teams skyrocketing to 2k ratings with ease, with none of the risk involved in competitive ladder play. Straightening out also ended up as being the complete disabling of the whole system while Blizzard investigates "current rating calculation discrepancies." However, Zarhym posted earlier today on the forums that Blizzard will be bringing Arenas back up and all ratings rolled back to pre-weekly maintenance status. All items (and Achievements) gained "illegitimately" will be removed, Arena points refunded, and all gems and enchanting materials returned. As far as that 50 Gold tip you gave to enchant your gear is concerned, however, you're out of luck.
