Revert level 90 Alliance XP change

Don't worry, kids. Your zero effort leveling method is coming back in a month or 2.

Occult Crescent will not have a leveling aspect to it, as mentioned in the Live Letter, that is being saved for Deep Dungeon in 7.3X.
The new exploration zone is exclusively level 100 content, just like how Eureka was exclusively level 70 content.
