Fun is subjective. I can have fun bouncing a ball off my wall two hours if I take enough dabs. In a game that's primarily time gated when it comes to major progress via cool downs and timers etc.. it's really up to you as an individual and the community/friends you make to make your own fun. The game provides little to nothing as a whole, for me personally at least. It just facilitates the place where you can make your own form of fun.
If you're looking for a game that has a foundation that is already just *fun*, in my opinion you're in the wrong place. You'd be better off just putting your time into a single player experience on console/PC gaming.
