It's apexis crystals and it's a currency used to buy worse gear than you can get from easier sources. In other words, useless. The fastest way to get them is do repeatable quests which involve killing one hundred mobs. That's it, no story and progression, just grinding. But it gets better. Their latest big patch includes more garrison minions (which get you free gear with a click of a button), more of these lovely apexis quests, an attempt to fix the pvp island, a new difficulty level for existing dungeons and a way to be synched in old expansions' dungeons. The last completely new feature the game got was selfie camera and twitter integration... Non-raiders are bored and it's justified.
By the twelve, just reading what I wrote makes me cringe at the state of that game... please let me stay! :'D
