All mages gonna use flame burn in the end and aoe fire. So fire is a must.
All mages use cc's: Tstorm, Discharge, and lightning. So wind is good.
As a m/k, you only use star of light and light charge.
Star of light: if you like your meteor, you going to love this. It is essentially the same except meteor don't get % bonus, which as you progress, meteor only does 2/3 of damage compare to any other spells per second. Star of light, however, get % buff from one of the elite skills, so gonna stay strong and hit like a fireball.
Light charge: is a ok cc skill for kiting and add in additional damages during the rotation. If you like to practice kiting, make a scout alt and practice with wind arrow.
Holy Light Strike sucks period
Every mage gonna end up with 20 second flame burst and flame is the best choice as starter attack. You got discharge for 100% stun rate rather than 30% from holy light strike. Normally after flame, you'll cast lighting to make sure mob stay away from you, or use light charge to run away from mob, so there is no really use for 30% stun (by the end of 2 seconds, the mob will already got 1-2 hits in).
As to why the m/k still have to follow the flame burst phase like any other other mage instead of Star of Light phase...is because star of light isn't reduced by casting speed reduction. Apparently all channel skills don't benefit from casting speed reduction. So in the long run, with more casting speed buffs (recent one being the casting rune), m/k going to lose out.
