Obsolete? I don't know what you're talking about. Yeah they're remaking patrols, but they're not changing every enemy on every planet to meet the new level cap. People will still be going to earth to get 100 headshots. New players will need to run the old raids to understand how the raids in destiny work. And strikes and being revamped as well, so I don't see how any of it will be obsolete just because there's a new location.
