PLEASE decrease the odds of full AP teams in ARAM

It is literally a loss at champ select.

I know, I know....You don't have to build them AP, and there are rerolls. But still, I shouldn't play 10 matches and have half of them condemned to loss because of being unable to acquire non-AP champs. I consistently burn both rerolls to try and avoid full AP but get shafted with guess what? EVEN MORE AP! This is almost not an exaggeration, which is the sad part. It is even more absurdly frustrating when you, despite your teams best efforts, you end up with a full AP comp. Then! You look at their perfect comp and just KNOW that you will win early game. But once the spirit visages come out, it's a done deal.

I think an easy way to fix it would be so that if you reroll, it alternates between a random AD champ, and a random AP champ.
