Not questioning that they have alts. Clearly thats expected when you have higher ratings. But I am talking about competition at higher ratings such as their mains are at. If there was real competition at 2600 CR they would not be able to maintain their amazing record and rating.
High end competition does not mean log your #5 alt and queue up at a much lower rating.
What I consider to be high end competition is actually queuing the characters that you have in the top 10 against other players in the top 10. Playing constant series' as different setups and maintaining a balance of queuing those characters often and actually climbing and falling in rating as you can see most of the players in the top 10 on the US have done quite frequently.
