It's not as much a dps improvement, but I also like how arcane barrage having no cost or cool down means it can be spammed when having to move with no time to build up charges. Orbs can of course help mitigate this, but just alone the mobility and speed boost is nice for questing or oh *!@# movement moments
Unfortunately seems that mages are going to get nerfed again, how much of a difference it will make only time will tell.
Hehe retail gnome
Now that the other specs are viable we can put arcane into the ground though...
Arcane still requires a bloody PhD to play its rotation optimally, so I reckon I'll just stick with Frost even if it does less damage than both Arcane and Fire.
