I know this should probobly go in the mage build section but i figured id have better luck in a response here.

So i have been kinda out of the loop since the expansion and was wonder for a maxed out endgame mage what is the ideal gear/pet set up at the moment? Also curious on whay mastery is the best to go for atm. Thanks in advance for any answers. (Currently running arc ring/plan pend/slate chest/glint helm/arc staff)
