Crit chance runes should be removed, or made multiplicative.

As in, instead of granting X% crit chance as a FLAT value, to a MULTIPLIER. Eg. You have 50% crit from items. Flat 10% bonus becomes 60%, a 10% multiplies is 10%(50), for a 5% bonus. Numbers would have to be changed obviously, but this prevents crit runes cheese, and can't be abused to the 100% crit chance hard cap.
