Nice job op
As other people have suggested, you may google different types of mastery setup which may suit you. PI doesn’t really matter, but it is advisable to have a look at your mastery again especially if you haven’t changed anything since you started playing. The goal is not to have high PI, but to have the best mastery set-up for your best champs. When I finally invested in better mastery (without suicides), I noticed huge increase in damage and better gameplay in many different scenarios. Choose what suits you best and what you want. Congrats on your R3 Apoc!
