As the title says, this is meant to reduce the drop of those bosses ‘‘minions’’
The drop of those bosses are way too abusive as ‘‘Shoot the core’’ barriers was or even more, if you keep shooting the ‘‘minions’’ of those bosses, you can get up to 20 fp in some mins, different weapons, and obviously alot of points, Making it the perfect way to win a Daily/Weekly challenge. (And probably to increase Tier too)
