Volatile Light:
Before: Rounds fired from this weapon have no damage falloff, Overpenetrate targets, and ricochet off hard surfaces. Projectile damage increases after bounce.
After: Rounds fired from this weapon have no damage falloff and ricochet off hard surfaces/ Projectile damage increases after each bounce; Projectiles can chain between targets while damage is lowered.
This makes the gun better in PvE as a contender for Add clearing, and in PvP it makes the perk Reliable.
Upvote if thy agree.
They already discussed ages ago when they buffed it originally that giving the rounds "smart" bounces isn't feasible due to the enormous computational strain that could create.
