Hello, I know that it is usefull to put out Frintezza when you have pvp with classes which use skills as mirage, switch etc. cause of reflect.

I know just I have to do it, but could some1 exactly say me why?

if u hit th with mirage, there is a probability for u to lose target
if u have frintezza on u, additionaly whenever he hits u, u reflect dmg back, what causes additional chance for detarget

ah yes, simple
