I don't have a problem with a Level 90+ Master. Once you've hit Master you've played a fair amount of ranked rounds, maybe you get a little bored and start playing more Alt.Shot and Matchplay, then your XP points go up and average stalls. If you see a high level versus, what you believe is, a low tier check out their stats. I played a level 80+ Tour pro and thought uh-oh, checked his stats and his GIR's was 40%. My point, some people struggle, some people don't.
I do, however, have a problem with L40+ Hacks and Level 89 Amateurs
