The polaron weapons proc ( drain power ) does
Not work
Tested all three types I'n fleet pvp and didn't
Drain any power from my fleetmates after several
Minutes of bombardment from 8 on my cruiser

Tested the STF version
Tested the story reward version
Tested the polarized disruptor version
( the disruptor proc works )

I would change these out for another weapon
That has working procs

Tets seem to be the best for me
