Have you solved your conundrum already?
Sorry to see none did reply to you. I`m playing ships a month already, I was frustrated about same, but then I realized that hit chance for your ship against opponent is comparison on toon levels, stars, gear, mods and ships level, stars.
So if your biggs is G8, some 2-4* mods agains opponents Biggs G10-11, 5* mods, then your Biggs is 2-3 times weaker. It is obvious that your Biggs will miss most shots.
Imagine Arena you go against G10 team with your G8 team. Of course you will be destroyed.
