Hi, I was playing some coop and ran into a situation where I was attacked by a large number of sera t2 gunships while I only had a cloud of t1 inties (unit restrictions). I sent my inties to kill the gunships but a while later all my inties were dead along with some of the gunships. I tested this further in sandbox, 50 gunships vs 50 inties, and found that all t2 gunships are able to hit t1 inties. The cybran gunships were the most effective (rapid AoE weapon), aeon second (slow AoE weapon), sera third (decent damage and tanky), and uef fourth.
Now, these situations aren't exactly common. Gunships and inties aren't usually made in equal amounts. If equal mass was spent into gunships and inties, I believe inties would have handily won (possibly great losses vs cybran though). Microing the inties would have also allowed them to avoid most of the projectiles. Smaller numbers will also probably favour inties since they are less likely to be hit. ASF also perform very well against t2 gunships, invalidating the entire scenario. Regardless, it doesn't feel right to me for t2 gunships to be able to hit inties with any sort of reliability.
Not really sure what would need to be done to fix this. Make inties fly higher and shoot downwards? I'm sure that would come with its own problems.
Steps to test this yourself:
Spawn high hp buildings (HQs for example)
Spawn enemy gunships and attack move them into the buildings
Spawn inties and attack move them into the gunships
