Top 2 GAC Kyber spots.... really?

I hate Bus 74 with a passion, but I gotta admit that he/she built their roster smartly with GAC in mind, not putting relics on lots of toons to have easier matchups. I've been checking their GAC history from time to time and the opponents Bus 74 gets matched up with are a joke. They just exploit the matchmaking to the max, that's all it is. It's not so much skill in terms of fighting that gets Bus such a high GAC rank every single time, but it's the smart way they built their rosters specifically for GAC. I'm not blaming Bus here, as they play by the rules (I hope they do at least), but I'd like to see a change in the MM algo to prevent such playstyles.
