High dps/spread shot characters + split shot = heavy frame drops

[delayed]

Vyper, Calico, Wraith, Haze and potentially others with split shot and fire rate cause frames to drop heavily by flooding particles everywhere. late game with team fights with this causes the game to drop even more frames. The addition of an extra 5th shot caused this to be even worse..
