Now the Cybran have recieved a huge number of QoL fixes and some tweaks i'd actually ask the same team that did it to look into Aeon.
To summarize it the Aeon are the most micro-intensive side whcih plays a little more defensive than the other factions and also is being infamous for being a one-trick pony which is "spam auroras, then rush harbs".
While they certainly can put up a fight, there are number of small improvements which could make a life a little better.
Their t1 subs lack the deck gun which is certainly a disadvantage. As far as i know, the reason for this was that every 'chrono' weapon was supposed to have an EMP effect. The idea got scrapped but they never added a deck gun back.
There is a similar story with Aeon t3 strat which is regarded as a worst strat agains units. While all strats have a token AA gun the Aeon one have nothing. It had a flares i believe to trick SAMs and guided missiles but those got removed too and he did not get a gun. Another thing with it is it had a slight tracking capability on the bomb in vanilla which compensated somewhat for a poor AoE.
The Obsidians are considered to be a kinda bad unit because they lack both range and speed and the Blaze is just something you dont build at all until completely desperate like a Titan. The reasoning for this was a hover flak along with mobile shield that allowed you to fight a navy with ground units or supplement them and having a great t1 hovertank but maybe its time to re-evaluate it.
Their MMLs are wildly inaccurate with the wave pattern for the missile which is another half-baked feature that should either be implemented or just straight-up removed.
And a last thing is that every single saucer-like Aeon t4 is bad. Idk why its a thing.
