If some of the screenshots I've seen are to be believed, during this downtime some players were looting upwards of 20,000g from a single mob, if those same multipliers were applied to xp it's likely that not only were people playing during this time able to multiply the gold in the economy many times over but we conceivably instantly got a lot more 60's.
The rollback sucks and all, but frankly I'd rather lose 7 hours gameplay than deal with the ramifications of this error.
