so you can be in invite yet not allowed to do this... nice. Also this just plain looks bad.
If you are invite, but don't play lobbies in general, then you probably wont be interested in this to begin with. You also never gave any insight as to what makes it bad...so...? I'd honestly like to hear it because I'm not really seeing the downside here. It's for people who want consistent lobbies at a higher level, those not interested aren't affected in the slightest and they plan to help competitive TF2 as a whole with some of the proceeds.
Also, in the FAQ they went over that they were trying to find more ways of allowing people that can't pass the easy check of steel+ and ranking, to get in as well. With that said, with the completed product I'm sure any Invite player will be let in.
