The Crimson Binome
Hero
It's not a significant bonus, and it doesn't scale only by number of attacks. Critical successes reward attackers in proportion to how much damage they deal normally, without accounting for critical successes. You could replace the current crit rules with "all weapon attacks deal +1 damage per die" and it would have very little effect beyond smoothing out paladin bursts.And yet no one cries about crit successes heavily rewarding those same people beyond always hitting.
