Why in gods name am i getting 140k power teams in arena gold 3 ?

That's insane. I used to be in gold 4 consistantly until i put a single champ in defense during the event. I quickly went down to gold 1 and had to fight my way up again, but now i cannot get back to gold 4.

There needs to be another tier. Maybe gold 5 and 6 or a platinum tier after gold 4.
