Roll a Worgen fire PVP mage with engineering. First of all resilience no longer reduces chance to crit so spamming Scorch while kiting away will procc tons and tons of instant Pyros that will all Ignite! Heres the specc - http://www.wowtal.com/#k=ketU7Xpb.9zi.mage or something very close to that with the focus being a 10% chance to remove all movement impairing effects and sprint away, Worgen sprint, engineering sprint, blink sprint, and of course when cauterize procs you pop your instant Mage Ward which will dissipate from absorbing the fire damage and pop ANOTHER!!! sprint. You will be able to flee when you want, chase down anyone trying to run away, and all while spamming scorch and instant pyros. Thats 5 sprints for those counting, making fire mages amazing in BG's! hope they dont nerf it
