I'm actually very happy for IE's change
Last year, I used to run the 45% Bonus Critical Damage page, which make my crits deal 295% AD. I could kill absolutely any squishy in existance, and it was great! But those damn TANKS, like Galio, and Rammus, they would literally just ignore my damage as they flashed up to me with their taunts and started spamming their laugh as I was physically unable to deal any damage to them whatsoever with my attacks as they proceeded to 100-0 me with their mere base damages alone.
I am MORE than happy to deal less damage to squishy targets if I can finally fuck Galio where he deserves it most.
