Majority of your searches in champ lv is paired with master levels or low lv champs. The main difference is amount of cups you can win. When 3800 up you may have to search 1-2 h to find a relative good match of 6-15 cups. But in general you get mainly 1 cup matching and up to 3 cups if you are lucky.
some searches you spend 500-800k gold to find a decent raid.
Its logic because majority of high lv opponents are less but pretty boring to sit and click next 500-800 times.....even at 3600 takes time to find something which is worth raiding. You need to have a lot of time and dedication to endure it......or you gem anything that comes your way.
