Wow gold players don't have any nasty DoTs on you that would break it.
I was going into battle with the old, stand-in-one-place-and-unload mentality that the Arcane tree used to require. That idea is gone now. The Arcane tree is now designed for mobility. Spells like Arcane Blast and Arcane Missiles that require you to stand still and cast are relics of the past. The primary PvP spell for Arcane Mages is now Arcane Barrage. An Arcane Mage should now be constantly moving in PvP, running and Blinking from cover to cover, launching out Arcane Barrages every three seconds, applying Slow when needed, squeezing in the occasional Fire Blast or Arcane Explosion as the situation dictates, and pausing only to rattle off a truncated Arcane Missiles whenever Missile Barrage procs, or to throw out a Polymorph when control is needed.Arcane Barrage provides strong, consistent damage while on the move, and burst damage comes with decent frequency whenever Missile Barrage procs.Presence of Mind can be coupled with Frostbolt for snare purposes, or Arcane Blast when raw damage is more useful. Arcane Missiles is still useful in the same situations it was pre-patch, as a way to ensure damage when the target is about to duck out of line-of-sight.Survivability is low if caught in the open, but this spec provides a surprising sense of slipperiness. Use the mobility provided by Arcane Barrage to pillar-dance, ducking back and forth behind cover between casts. Blink and Frost Nova provide escape mechanisms, as well as instant-fade Invisibility as long as wow gold players don't have any nasty DoTs on you that would break it.
