Give Cybrans the Aeon Absolver, simple as. You can even do some sort of community design bounty for people to design a version of the Absolver that best fits the Cybran aesthetic.
The logic seems pretty obvious to me. Cybran suffers from the inability to deal with mobile shield spam so a unit that specializes in killing shields would greatly assist in making loya and brick pushes more efficient. Aeon is also arguably the most shield centered faction rn with the fact Asylum costs nothing and is amphibious so it makes zero sense for them to have this unit.
This also gives Cybran a great way to handle sniper spam since they can make some Absolvers to kill the shields and then have 3-4 trebuchets that insta kill the snipers.
Also don't need to read any more crybaby posts about UEF or Aeon rambo shield ACUs.
