This doesn't track at all. FPS such as Overwatch have characters that move faster and mechanics that are more complicated than Quake, even if the time to kill is higher. Any given MOBA has dozens of complicated skill interactions that change every match. I don't love Fortnite, but building structures while shooting requires pretty demanding execution. "Simple" isn't the term I'd use at all.
