I mostly miss having ‘Specialized’ careers.
Lot’s of players had viable business ventures happening in-game. I’m talking about providing services in-game such as Exploration Bookmark Service, Industry Mining Service, R&D Blueprint Service, Manufacturing Service, Corp Formation Service, Structure Anchoring Service, Jump-clone Service, Salvaging Service, Standings Service, etc.
All of those ‘Specialized’ services have been made obsolete due to CCP turning the game into easy mode for instant gratification.
Also miss the Jukebox, In-game Browser, Evelopedia, Eve Gate and Captains Quarters.
