Restricting team builder to lvl 25+ is hateful

While team builder was active for us sub-lvl 25 players I was using it to practice all of the different roles, depending on what I fancied each day or what I thought needed improving. Since its restriction to lvl 25+ players I'm stuck having to wade through the mess that is blind pick or draft.

Blind pick means that those that are fastest at picking a champ and locking it are the ones that get to play the most coveted roles (generally mid). Also, I've lost count of the number of times I've played on teams with three ap mids.

Draft pick isn't much better. Typically, I will have to go through 3 or 4 drafts before I get to play an actual game. Obviously, people are queue dodging because they haven't got the champion or position they want. It also means that, unless you're lucky enough to be first pick, you will not get the opportunity to play mid. Incidentally, my impression is that I do not get selected to be first pick anywhere near 20% of the time. How exactly are you choosing the order?

Both of these setups (for blind and draft) seem designed to encourage the worst, childish, tantrum-throwing bahviour as that's what is most likely to get you what you want. In my experience the more patient and reasonable players will just let such a person have whatever they're screaming for, not because it's fair or good but because it's easier.

Maybe this is what Riot have intended the experience for sub-lvl 25 players to be. I just have one final question then:

Riot, why you got to hate like that?
