Yup more simmable events would be nice to have. But, I can't help but think burnout is more of player problem. The issue stems from FMO. In reality, nothing happens to you or your game if you step away or miss an event. Players need to to do better in managing their lives to avoid burnout. If you are feeling burned out take a break. Personally, I have stepped back a few times in the years I have played this game and It has had zero impact on my position in the game, but has warded off any feelings of burnout. There is always someone better and someone worse.
One does not have to be the tip of the spear at all times, especially when it doesn't mean anything.
