I got that from here; Arcane Mage DPS Rotation, Cooldowns, and Abilities (WoW MoP 5.4) - Icy Veins
As IceMannn says, disa
as a general rule that is ok to use but it is not optimal as you are never using missiles procs or cds (AP/AT) and that is a major dps loss. honestly the rotation shouldnt change based on how many targets there are together. would you be willing to implement that as, at very least, an optional rotation selection or something like that?
