It's nothing substantial so far... he was pretty much watching his crit% go down as he leveled. The 5% thing held at other levels, too (on an aside: it might be slightly higher than 5%; Puro's data is the only place I've seen it be that low but then again RN gonna G... and ain't nobody got time for the 750k hits to get another sig fig anyway). And that yes the crits are more than 1.5x buff now.
