I don't entirely know how feasible this is, but my thought is to have a command that a user could run that would:
1. Take the last fainted pokemon
2. Run 2 damage calculations (one for if the opponent has full health&defensive stat, and one for no evs in both)
3. Lets you see what the chances were for the final move to kill assuming no crits, with both situations.
This would not only let the user see whether or not their crits mattered, but if the damage roll mattered. It would take into account the user pokemon's actual ev/ivs, but make assumptions for the opponent's, since that's what would be possible in the damage calculator normally.
