It probably doesn’t need to be completely rewritten, but at least add a count of how many heros of each rank to the equation to put the people that sacrificed/deleted most of their lesser heros to max ascend their pvp heros, presumably just so they can take advantage of being in a lower tier, are competing against actual peers. There’s no reason people with multiple teams of fully ascended heros should be competing in the same tier as those of us that have only been able to ascend our heros two or three times thus far.
It’s well known that the power levels are not at all an accurate tell of a teams capability and as such, power is an inappropriate measuring tool while splitting people into tiers based off the total number of heros of each rank should give a much more balanced gameplay.
