Thank you for the test. But how did it change from the live server?

It used to be ( your magic resistance - anti_magic )
eg: you have 50% MR and you opponent has 50% AMR, the end result will be as if you had 0% against him (50 - 50 = 0).
Now if you have 50% MR and you opponent has 50% it will knock down 50% of yours = 0.5 × 50% = 25% which leave you with 25% MR instead of 0%

if you had 100% MR it wouldn't make a difference between now and before, the end result is 50% in both.

i think MR and AM are not correct with melee players.
Healers get tones of damage.

GF goal was kill the "map1killer" mental warriors.
GF goal today "map1killer" Healers and Archers?
