I think they don't make it a mechanic because of the fact that it negates crit damage. Like theres kassadin with his 15% reduction to magic damage passive but like this champion nullfies crit. Would have been cool if it reduced crit damage by 40%. Like negating critical strikes takes it ti far, reducing there damage is fine.
