Actually there are numerous threads stating after TSF was released (and crits merged) the amount of 'extra crit' needed to hit a higher level opponent was severely lessened, if not removed outright. My own parses getting 100% crit rate with 102 crit chance on level 98 enemies seem to support this in some small way. not the place to debate this though hehe.

This will help me further test this though.
