Revert level 90 Alliance XP change

[MitsukiKimura]

I dont see the problem with the nerf.
Getting 1 lvl in under 20Min without any effort is too broken.
Im surprised they waited this long. It was obviously not intended.
Complaining that 14's gameplay is stale and boring but willing to spam the most boring Alliance Raid. smh
Make up your mind, guys.

I'm sorry but I will take any EW alliance raid over 1 2 3 spam of Crystal tower or labyrinth of the ancients. Which requires no effort.
