borg force shield upgrade needs changes

[poland spring]

Why would borg shields reflect projectiles? Seems OP.
Borg shields should protect them from lasers and bullets but also drain their batteries by a good amount each time they get shot at.

As far as I know they do do that already, while under sustained fire the power cost constantly increases. The intent was for people to be able to overwhelm borg shields like that.
It's just that projectiles are reflected as well, which would make it quite hard to keep shooting at a borg.

What if they were DEflected instead, ricocheting in a random direction away from the shooter most of the time.
