fair, and not gonna lie when i first played the game, it did felt like from marcy to gremory it was like easy,normal and hard difficulty,
and a idea did just got up about removing marcy crits, maybe leave the ability to crit to vepar as rogue playstyle can rely on that, with marcy strengh it would be fair if to remove her ability to crit, and gremory dont exactly need crit when she relies on magic, but again it more your choice what ya do about it
