I sometimes feel sort of bad that the B8 Aurochs went from a B8-only team to sort of its own separate entity that a few B8ers happen to be central contributors of. The B8 thing, at least at the time, just wasn't really sustainable since there were only so many available players to draw from (9 people is a LOT of people to round up for a match every week, it turns out), and as we started grabbing players from other teams and communities to plug holes that we needed, our team started to develop a really strong nucelus with those guys and we wound up building ourselves into a more serious, high-level highlander team (albeit one that still doesn't take itself that seriously). The B8 Aurochs team was fun but I don't think we could keep it going as a solely B8 entity for longer than a season, and the team it has developed into now is one with a strong identity all of its own and something I'm very proud to be a part of, the only unfortunate part being that we're playing on such a high level now that it sort of shuts out a lot of people.
This, of course, shouldn't stop you from trying to get a new B8 team together! Competitive TF2, even on just a PUG or lobby level, is an absolute blast, and it's where TF2 really comes together as an amazing game in my opinion. Highlander in particular continues to be friendly to all levels of play - the major hurdle to overcome, in my opinion, is just getting together a full team of people who can and want to play regularly. 6v6's easier but tends to be very soldier/demo/scout-centric.
