The Normandy (and Normandy 2) are frigates (small ships)considering that when it's upgraded it's able to destroy a collector cruiser relatively easily, i'd say it is definitely a warshipNmil-ek said:Turn the Normandy sr2 into a giant fucking warship, okay maybe wont help defeat the reapers much but would be fucking awsome seriously I save your asses twice I want a warship.
Edit : oh and my money for ME3 is on "hopefully you've made some friends!" gathering of Rachni, Geths, Quarians, Citadel Council Races and maybe the Terminus systems.I don't think they'll implement real space battles since it would require programming a completely different combat model but maybe something like the end of ME2 where you wished you had upgraded your ship.The "real" fight though will definitely be Shepard+2 since he's just that awesome!
