Randomness is a central aspect of Pokemon battles. Crits, High power but low accuracy moves, IVs, Natures, Shiny Pokemon, Encounter Rates, Capture Rates, Slot Machine mini-games, need I go on?
If they take away crits, you're just going to cry about how only 1 offensive Rock move has 100% accuracy and how Fissure should have a higher accuracy because you get so few uses of it.
