Yep, for ex. 50% crit meaning you could do: "normal hit a minion, crit a champion, normal hit an minion, crit a champion..." would be a rather big buff.

You could then at certain points (20%/25%/50% crit) just stop buying crit and instead focus your money on more AD/AS/ArPen and rely on your mechanical/timing skills to get near 100% crit on champions...
