"Epic points" are simply a prettier, more intuitive way of phrasing "You can run a max of two Huges in an Epic list, and you get a max of 1 CR-90." when you consider they'll make more.
Just because Epic Points range from 1 to 5 does not mean there will be Epics of every cost. I suspect we will never see 1 EP ships (you could run five of them!) or 4/5 EP ships that can't be run with the 2 EPs
