The problem is that everything that can be done to change crit's will impact the game so heavily, it will not be possible to play without adding some seriously high damage items in their place, which will then throw off the damage of assassins etc.

I think that logically, critting is the only part of league that must remain a chance based system. I think riot have tried to phase out parts of it's impact with the blade of the ruined king damage scaling on their hp but how many options to adc's really have at the moment other that crits?
