Am I the only one who think Domination is more appealing to mages than sorcery?

Totally depends on the mage and the circumstances! But yes, Domination is a fine option on quite a few.

Well yeah. It has nothing but damage.

Depends on the kind of mage

For yeah not sure about other mages

You mean as a primary? Because the only ones do that to get thunderlords. If you mean 2ndary, then no, almost all mages opt for inspiration 2nd or sorcery.

electrocute is good, but the others are pretty meh. Cheap Shot damage isn't that substantial, Taste of Blood has a 20 second cooldown for 10% AP healing (not really much of a substitute for spell vamp), and most mages can't use Sudden Impact. Ghost Poro / Zombie Ward are decent, but the <prefix> Hunter runes seem more catered to assassins because of the whole "unique champion takedown" thing

In my experience Inspiration is better, followed by Precision
