This probably should be moved out of balance discussion imo. It stopped being a balance discussion as per the requirements for that a long time ago.
That being said, the test @Lorem_Ipsum wants to do doesn’t exist in the way he wants it to. Taking away stealth from cybran is just dumb. At that point take away UEF shield boats and force aeon to make the same ratio of frig to bs as cybran in mass. It’s not a test of anything. A 2k player will destroy simply because of better micro and unit comp over a person with 100 games. I’ve literally played more games as Cybran navy than you’ve played games period.
You need air to balance out Cybran stealth which has its own whole can of worms when it comes to balance. Often torps are often best counter to barracudas if you’re UEF and don’t feel like making coopers but if you’re Aeon then just sit a destro on them. Tempest crush cybran bs but then cybran frig swarm can crush tempest as long as you micro frigs well. Usually you need t3 to counter Aeon destro spam since they snowball hard. It’s not a case of “oh this one unit is slightly weaker than its counterparts, must need a buff” it's how the whole thing works together.
