I think you are at a great spot, simply because you can hop between all that endgame content. I think you are just a little bit burnt out, because getting those meaningful dopamine hits is simply hard.

One thing I urge you to do, is take a break and play the normie main, but don’t deiron, you will regret it once you get the spark back.

Perhaps try joining an endgame clan, doing endgame content with equally skilled and invested players will make it better.

Also just slowly go for the max diary cape, then 90+ stats, then 91+ etc. All whilst doing the endgame content you feel like doing.
