To be honest, its actually good we get several clusters and crystals from the moraines.
The prices on some of the servers I have seen is downright ridiculous. The pricing needs to come down. Its shouldnt cost 3-4k in crystals (not including the cost of materials) just to make a level 51 piece of armor etc...

Likely this has nothing to do with the maintenance. Aether took an additional 40 mins on their maintenance to bring the servers up after the scheduled maintenance, and shortly after Mana and Gaia data centers started having issues. If anything the emergency maint, is in regards to that.
