Yeah, don’t know how i wrote it the other way >.<
Camouflage stacking seems like a bad idea to me, considering how expensive they are on power and crew. Also, they blow up last, so after a bit of fighting, you’ll basically have a dead ship that can camouflage a lot but not anything else.
What I’ve found to work well is an active defense. As said, carrier and a tight escort formation is amazing. Missile scrambler is a must, tractor beam(s), maybe even some point defense - are all far more effective than stacking 8+ repair units. Probably EMP is a good idea with the “retaliate” command, but I haven’t gotten that to work well for me.
a solution againts fighters is one cruisers full of autocannons 
it work fine.
