I am also only doing community events. Never touched the normal career. I like to do it like that. Because of the fixed car classes I often have to try something new which keeps the game engaging. And I actually like to use cars which are not fully upgraded yet. From my point of view, community events could be the main career path. There is so much more potential with the changing events. They could introduce the sponsor challenges from D4 for extra bucks. GO further and have prizes for taking part in specific community events like special liveries. There is a very engaging part hidden in the community events comparable to forzathon stuff in Forza Horizon.
