Alpha and Omega
See I can understand your point of view there. I look at it a bit differently. I'd say those PLAYERS are top tier if they can play a comp that no one else is having the same amount of success with. Don't think the Comp itself is top tier. I can't see it beating a variety of comps like disc warrior. To each their own pov.
I see what you're saying here, but feel that there is more to it. While they're obviously top tier players to make it to the very top, one could assume that they also had to defeat a large amount of disc/arms teams given the high frequency of facing that comp when queuing for arenas in this bracket.
