The way this game scatters modes willy-nilly around the waypoint menu is incredibly confusing for new players and incredibly frustrating to veteran players with slight cases of OCD. I think there's a better way.
Holo-Sim and X-Def should be part of Danger Room. I don't know exactly how it would work - if they'd be chips or a selectable permanent option on it but this would make thematic sense (why am I constantly letting Xavier's mansion be overrun! Why are Shield and Prof X both maintaining holographic training rooms!), it would clean up the menus and DR Merits could be rewards for all of them giving purpose to these dead modes once again!
Ultron should be included as a raid.
This way we'd have the following game modes/tabs on Waypoints:
-Hubs (these should be pulled out of story mode and given their own spot)
-Story Mode
-Terminals - single player boss runs (which would include One-Shots. the UI could probably be streamlined but the content similar to what it is now)
-Danger Room - single or multi-player scenarios
-Raids & PVP - multi player scenarios (including Ultron)
-Patrol Modes
I think broken out this way, it would be much clearer to players what everything is supposed to be. I know some tweaking would be required here and there but ultimately, they can't just keep adding modes and tossing them in that last tab (while strangely burying Danger Room in the hubs tab inside story mode). It Just Doesn't Make Sense. /ocd
