Set of remarks concerning the team builder
######First, if you too have an idea or opinion, tell me in the comments and I'll link it and add it here so it will be seen :)
Now, I've just tried the new, awesome feature, the Team Builder. But I have some notes:
###1. The aggresive sound
Maybe it's just me, but those iron-like, loud sounds that the teambuilder UI does all the time are annoying. Espetially when game is matched - I almost felt off chair. I'm ready to hear what you guys think about it.
###2. The necessity of jungle

I think it should be allowed for the team captain to create a team without jungler, because sometimes, the jungling delay get's really annoying. I already decided to buy Fiddlesticks and learn to jungle (I never did it and never liked it - too much responsibility for little me).
Jungle isn't necessary, I just found out.
###3. Lack of balance
It happens that guys from diametrally different level get matched to the team - they end up being called noobs and that's sad and unfair. I'm sure you're working on this one though.
###4. This - whatever it is:

It's quite a good idea to keep errors friendly for us stupid users.
###5. Any other ideas...?
I'm sure I'm not the only one who is very happy for this new gamemode - and I'm sure that finding problems in it is a very good idea to increase chances for improvement.
