[Bhisaj-Bal] work well with Split flight : more projectile, so more status proc to activate the healing ; and the accuracy reduction make that we are a short range, so take more damage, so we want this healing.

The viral status increase the slash damage from hunter munition ; the weapon have more than 100% crit chance so all arrow have 30% chance to proc, and we shot lot of arrow with Split flight make that the probability to have at least one slash proc is high.

[Vile Acceleration] make the bows mush more pleasant to play.
But it will be the mods to remove to play a riven.
For a riven, we want (in decreasing order) :
-Damage
-Multishot (will make easier to stack Split flights)
-Damage to Greener (+60% damage to greener add +156% slash status damage to greener)
-Crit damage
-Crit chance
-attack speed
