Where is team builder?

So I've been playing the new champ select for a while and I thought it was really cool. For a few games. Eventually it's really started to irritate me because it's always putting me in support. I want to play jungle as well but I've only gotten it once after 5 games or so. The way the whole thing works I don't think I'll be getting jungle that often now so I don't know how I'm going to practice jungling. I was told you've gotten rid of team builder riot. Which I think is pretty dumb. If anything you should've gotten rid of blind pick instead. Bring team builder back. Use it to replace blind pick. Blind pick is a shitty system anyways
