Managing aggro as a Mage

[Tharn]

Mage 2 simply waits till second 8 then goes all out. High damage instacasts like Fireblast and Cone of Cold are used. He starts on second 8 and does 3k damage total.

There is no difference between the two mages except that Mage 2 regenerates more mana.

Quite the opposite. Fireblast and especially CoC have such horrible DPM, that the few extra seconds won't help regenerate extra mana spent on those spells.

OTOH casting spells with long casting in the second half of the fight is risky, because then it's damage might be largely wasted.
