On The Topic Of Bots...

Honestly i have seen an increase in botting as of late on SR, even at level 30. I think it's due to the removal of Crystal Scar, which was the go-to for botters in the past. They just migrated to SR. I don't expect Riot to do much about it unfortunately, except to eventually ban the accounts sometime down the road (which really doesn't help).

What's Coop v. Ai?

I think roit really does not care about bots. They used to infest 3v3 and dominion big time but now they go between 3v3 and normal 5v5. Btw they been letting this happen for years now.
