I wouldn't pick extv for this. The channel isn't that populair anymore. It's basically extines personal channel where he dumps random videos...
This is kinda what I thought as well. Extv used to be the place to go for tf2 stuff, but that was a while ago.
If you look at extv's videos for the past several months, all the videos have between 500views and 7-8kish views except for Top 10 plays and MoG, which are moving to Lucky Luke's channel like plopy said, and in his recent vlog extine explained that the channel would be more about different games and random videos going forward. To me extv stopped being tf2 central back when teamfortresstv started taking off, and they are now getting similar view average numbers with 1/5 of the subscribers of extv. Now, it's possible that if we put jump stuff on extv those videos would be the ones that got a lot more views, but I'm not entirely convinced it's the best place for it.
I do agree that jump could do with more exposure though, whether it's through hitching on to an existing popular channel, or getting better about marketing and advertising and making content for the ones we already have. I think we definitely need to work on some formats though. So far, streamed races have been chaotic at best, either the streamer watches the pov of the person in first place or clicks between people randomly or tries to fly around in spec. There's no really good system in place for streamlining how jump races should work, and how best to display them, which could help a lot with making a unified experience to show around to people.
I'm also not entirely convinced that jump wouldn't fit into GDQ, but that's another discussion.
