If we assume stat sheets are without ME applied, Lancelot with Arondight had an utterly insane statline: A++ STR, A++ END, A+++ AGI, B MAG, A+ LUK (Protection of the Fairies). I've been going with 'ME adjustments are built in', or don't affect the exact rank because they tend to be out of proportion with the supposed rank of the thing. XD
