For me, the asymmetry that I hate is not between the two sides in the CG. It's between the Elite: Dangerous players (flying spaceships) and Elite:Shonky-Call-of-Duty-Knockoff players (running around in ground CZs earning 5x the bonds for the same effort)But regarding the asymmetry, I´m sure both sides would have had Odyssey commanders in their ranks if they just had a place to fight against each other.
It's especially ironic when the CG rewards are spaceship paint jobs.
I know none of this is the on-foot players' fault, it's FDev's fault for not balancing things. Doesn't stop it being extremely aggravating
