My friend, who is really experienced modder with a quite bright head is going to make a job from it, like you've done... While I shall not.
Even Punics can't hold so long, as wall of Halcyons. I see Epoch-class as an expensive ship with large amount of HPs and armor, but less than capital's. They are weaker than Punics, but not so overnumbered as Halcyons. They can't effectively tank anything, but incoming waves of small crafts and small pack of non-capital ships.
The mods are not paid to mod. They haven't made a job from it, in fact they are always working at late hours because during the day everybody works.
Look, when most of the developers and some testers alike told you that implementing another carrier into the UNSC fray as either a cruiser or a capital won't work, you should start thinking "Hey, maybe I'm wrong!", maybe because we've been working on this mod for some time (i.e. years) while you created this topic the day the mod got released. Not even the day after, the same day. But I'm sure you're more experienced than us and understood in less than 24 hours what we didn't in years.
Just as you refuse to believe us, I refuse to insist on making you understand it won't work.
Live Long And Prosper.
