I don't see the issue. Black Knights, as Negation might suggest, are designed to be difficult to critically hit. If you walk into a fight with one with good LUC and 5 SP in Negation and are relying on your stats and weapon stats, then yeah, you're going to have difficulty. I don't see the need to force an active component on Negation when you're not using any active component for your high crit rate. Not to mention that there are certain classes that can still pull off crits against 105 Crit Evade, namely any Archer using Bows, Void Assassins with Veil Off, Axe Berserkers, and so on.

Hope that was 'direct' enough of a response for you.
