Ships would still be used to get from Orbit -> Destination. My only complaint here is that I believe Guardians should START at the Tower as a default upon logging in. (Others have raised another interesting idea of being given the option to return directly to Tower following a mission's conclusion). Ships would still display prominently when traveling between zones. I (and apparently many others) would just like to have our characters log-in directly at the Tower, seeing as its supposedly a Hub, and as far as Lore is concerned, the home of the Guardians. Doesn't every great journey start with you leaving your home?
