I hate to sound pessimistic cause its not in my nature but I feel the TF2 competitive scene in NA isn't going to survive the growing pains this league will experience. I hope I am wrong but I foresee a shit season and the loss of a huge amount of players as a result. I just wish we had another option.
I experienced this exact thing back during Quake 3 Fortress in the early 2000's. The competitive community was left with only 1 option for league play and the guy who lead it was an uncompromising asshole. It was our only option back then, so we had no choice but to play in the league or not play at all. The competitive scene in Q3F never recovered.
Not that anyone would care what I say about this but I've read how sigafoo has commented and reacted to many things over the years on this message board. FFS, on page 2 of this thread he literally posted screenshots of bad things people said of him in the past. He had that shit saved on his desktop and now he is going to be the end word for everything that impacts comp 6's. Red flag for the type of person you are dealing with IMO, especially the admin.
I'm sure some witty reply is incoming, good luck this season friends, I really hope I am dead wrong cause I love playing TF2 6's and like I said, we have no other options.
