I like the balancing changes... so let's skip to the question that many have asked...

THE ANSWER IS IN CHANGES TO ELO
I think the answer to BOTS is learning how to make ELO work for level 1 accounts fighting eachother in high leagues. You just can't give someone 10 points for beating a level 1 account in silver-diamond league.
Get rid of that that and say that if you loose to level 1 team in diamond then OBVIOUSLY you don't belong there and you should loose a decent amount of points.

While they may still get their quest rewards beating another level 1 ... they'll be doing that at lower levels soon enough.
