yes. not as powerful as it was before.
now you can get a +10 to positve stats and a -10% to negative stats.
so if your gun shoots normally 100 it will shoot 110 now, and if it was 200 hull using it uses 180 hull now
if its cost was 5 million, its now 4.5 Million.
while 10% and -10% on postive/negative stats doesnt seem like much, it really adds up when all your ship parts are Compacted. 10% more gain for 10% less Costs. it will easily make your ships outperform your enemy. this is the difference between an American army tactic of precision and high quality vs a Spamming low quality ships for Horde tactics.
these gains arent big enough to be horribly game inbalancing (hell, months of work then having to collect all those annoying minerals), but if you got the nads for it, it can be a big boost to your abilities (just think of the gains to power generation with the loss of power demand. shields may be a viable defense!)
