You're an unusual player, then, and the game is probably not quite catered to you.
I'm at 200 item level, and I raid twice weekly and regularly run mythic+, dungeons, and do world quests and covenant activities. Of course, I am not striving to clear everything as quickly as possible. Maybe if you, in the next patch, just reduce how much you do in any given day, you can stretch out your activities. For example, you don't have to do every calling every single day. You could level an alt, too, for a while, exploring a different covenant.
