PPB Rebalance II: Weapon Mounts Revamp(please read)

[Captain Kwok]

I think what you are proposing is too much just to balance a single weapon. If you boost the research cost to Phased-Weapons then it is more likely that once PPB appears it will arrive at almost the same time as Phased-Shielding, so it turns out to be a short lived super advantage (like a cloak level) and while remaining an effective weapon - it wouldn't be too overpowering.
