buff Hound, Cerberus, Vanguard, Mudskipper, Buffalo MKII armour and hull
Swap the venting elite effect with reduced EMP damage, but make the reduced EMP damage act on maximum level when a ship is without a shield. Make that effect elite though, to clarify
Buff Derelicts by giving them significantly more hull, armour and mobility. Swap Neural Link with Automated Fleets. Nerf Radiant.
Profit?
Or alternatively just buff Hound, Cerberus, Vanguard, Mudskipper, Buffalo MKII
These kind of ships are what is supposed to benefit from Polarised Armour. That and Enforcer, Manticore...
But swapping that Elite effect with that EMP effect would actually make Polarised Armour significantly more versatile.
