Personally I'd love to refit a nova class (rhode island varient anyone?) on a couple of characters, depending on how a player refit system might work. (I'm in favor of a point system like has been suggested in numerous threads)
That said I'd also love to see some new cryptic ships as I'm not going to always want to refit an older ship.
I for one and in no rush to see the level cap increased. All it delivers is a new artificial cieling with us all flying even more ridiculously powerful ships. We will be even more ridiculous as fleet admirals running about sniffing flowers and taking water samples from the pools of barren worlds. We will simply have the advantage of doing so as an away team from a dreadnought.
The other major disadvantage is in all likelyhood all the existing ship models become obsolete. We are then thrown back a tiny number of new choices and a long, long wait for the expansion of ships again.
Say NO to a universrse filled with Fleet Admirals!
