Yeah, just I want to quickly point out that running tournaments is ridiculously complicated, and making everyone happy is never going to happen. There were decisions I made in REALTourney that I have come to regret, and it's stuff like this that makes me hesitant to run tournaments ever again.
The notion that tsc had some kind of benefit in making the call that ash was good to play (whether it was the right or wrong decision) is not rooted in reality. I think if tsc is guilty of anything, it would be overbooking himself in what he was managing. Running both the tournament and the stream is not typically a good idea.
All this said, ninjanick and company have (across all tournaments of mine they've participated in) been the kindest, most easy-going participants I've ever dealt with, so I'm assuming that there were some serious mistakes made by the tournament staff. I hope this can somehow resolve itself, and I do hope that you would give tsc, one of the hardest workers behind the scenes in tf2, a second chance should he ever run another tournament.
