Ok gotcha. I recently got Arbiter so ill swap Seeker out for her once i have her built.
You mentions that no one can have TM boosting masteries, What is TM boosting?
Hmmm... Ok ill look at my Cruel and Savage. I was already looking at swift parry since i had 6* speed boots there and the 18% speed. Savage and Cruel still beat that set out though for Demethya?
tm boosting is short for turn meter boosting. any mastery that increases a champions turn meter, like cycle of revenge or arcane celerity, is one you'll need to avoid.
