Bots in ARAM and Dominion?

I've been seeing more and more of a rise in bots in normal ARAM and Dominion games over the last year. I've seen a few posts saying they are only in low level gameplay, but playing Dominion and being the only human player at level 30 is a bit ridiculous. Its almost a waste of a game mode now. What is being done about this? There is not report option for this at all?
