Was planning on playing arcane mage again (been a few years since i played it beyond solo questing and heroic dungeons), was curious what stats i should go for? What embellishhments i should get (I was thinking Blue Amice and not sure what else after that). Also, is Shimmer okay to take for pvp or is the stun-break of Blink absolutely necessary?
Haste is the main stat. Take shimmer, it will save you and help you get kills.
