Perfect Block mastery question
With the recent change in parry description and parrys apparent relation to perfect block mastery I had a question. I maxed perfect block now before i had zero points in it. So that 4% chance for perfect block, is it out of 100%? Should I see it that way? If it is 4% out of 100% chance then i dont see value in investing points in perfect block with the huge attack and large health pool champs and game modes coming in. Chip damage is always going to happen. Am I seeing it correctly or is there another angle to this?
