FW vs OG - Showing how stupid a stat crit is

I'm not going to sit here and argue whether it decided the outcome of the game (there were obviously a lot of factors), but there were two critical points where FW won a key battle because Cait got lucky with 2-3 crits in a row, there is no denying that.

Then, the baron steal -- even the analysts saying Jinx was UNLUCKY at that point not to crit Baron once that would've prevented Cait from getting the steal.

Why leave a stat in that can decide games purely on RNG? You removed dodge so long ago, why does crit still exists?
