Also, there is no balance point. I already tried to figure that out and the balancing issue lies directly with the exponantial equations, making it impossible to make a simple "after X avoidance, get Mastery" conclusion. From that same math I have also proven that;
* with SB on CD, you need only 1 Mastery Rating to make SB on CD better than Avoidance (at any level) up to unhittable ofcourse
* without any SB at all, Mastery requires insanely great gear to beat avoidance
* to get Mastery to reduce an equal amount of damage as it does for Paladins, you need 100% critical block
* the math needed to calculate mastery gain vs avoidance is severely more difficult than the math needed for ArP before they removed it.
