Although it may have been amusing in the moment to see Clockwork and Serv0 run double sniper and Shade run vaccinator, looking back on it, I actually find it disrespectful. People like me, but much more so people like Dashner, Extine, tsc, uberchain (and dozens more), spend a lot of time trying to promote competitive Team Fortress, with a goal of showing the larger TF2 and eSports communities that competitive is a serious eSport worthy of consideration for sponsorships and viewership.
If Froyotech doesn't want to scrim, that's 100% fine. If they even don't want to take individual moments or rounds seriously, that's also OK.
But if certain people on that team no longer take the game seriously, and care more about some gimmick like Fantasy than the game itself and its livelihood... Then that's a problem. A big problem. And although there's no rules against what Froyotech did, I find it a huge disappointment as a fan of the game.
