MR_SLINif this is the case, then you likely can run the pugs without mentors. it would become like any other in-house pug group except it would have an enticing name. any players of relative skill level could participate, and UGC players could fill the mentor void to help the brand new players. I was under the impression that the leaders of newbie mixes wanted pro/semi-pro players to take part.
I can't really speak for anything else in this thread, but I do think I can offer input on this point specifically. I think that anyone who has a firm grasp of the competitive format can coach a newbie mix, and I think others have said this as well.
That said, I think the reason that there is a big interest in getting players from the top levels of the game to show up for these events is because those players are known and recognized. They are the names from casts and youtube videos that sparked the interest of the newbies who are coming out to the newbie mixes.
It would be like having a pro football player show up at a clinic for high school players. The chance to learn from someone you both admire and try to emulate can do an incredible amount of work towards getting new players invested in improving on their own. That idea that they got a chance to play with what they consider to be greatness can't have a value placed on it.
I can remember pubbing against players like polk, milo, and others. Or having scrims with or against people like ruwin, indust, memphis von, you, and plenty of others. Names that I remember watching in matches and casts that made me want to pursue competitive play. Players who's styles I have worked to emulate and used to guide my own improvement.
I doubt any of those players even remember me from the servers/games, but those experiences, more than anything else, fuel a new players drive to improve and grow on their own.
Pro and semi-pro players don't have to be a part of every mix, and I completely agree that teaching the same things again and again can be frustrating, and tiring. So don't show up to all of them. But show up to some, and more importantly, let the people who are running the mixes know when you are going to show up so they can advertise that some.
You would be surprised how many new players you will inspire to become long term members of this community without ever knowing it just by giving them a chance to play, even for just a bit, with you.
And if you are looking for some kind of return, those players are likely going to be the ones who follow you on twitch, and send in donations and things like that. You may not feel like your presence has a lasting impact, but I can promise you, that for every aspiring TF2 player, seeing names like Mr Slin, and any other player who is active in Invite, on Twitch or Youtube, or just in the community in general, it is an experience they are not going to forget.
