Just hoping to get Riots thoughts on Player vs AI

So I am one of those players that plays primarily player vs ai, but on occasion will do some ARAM and special game modes. I understand that many people prefer pvp but it just hasn't been for me at least up till now. Anyway, I have to questions that I was hoping Riot could answer.

1. Last year I remember the bots being slightly more bloodthirsty and better at combos. Now it seems that they retreat at the first sign of taking damage. I think that the change came some time around when they made bots better at dodging skill shots. Regardless, I was wondering if there are any plans to make a higher tier of player vs ai? Perhaps one with more champions, some better ai, builds, and strategies. I imagine it would be difficult to program a jungler bot, but it sure would be fun.

2. Would Riot ever considered disabling items like Sword of the Occult and Mejai's Soulstealer for Bot matches. As lame as primarily playing bot matches may sound to some i still enjoy it. And it irritates me to see those items roughly every second or third game. There is almost always someone purchasing one of them one their first back then proceeding to roam every lane taking kills. It also really detracts from the game when I am trying to show friends that are new to the game. I have always made a point of never purchasing those items as it feels like a cheap way to make my stats look good. I guess i have a similar reaction to someone purchasing one of those items as a person in pvp would to laning against a teemo or nidalee, lol.

Anyway, sorry for the long post, and I don't mean to come across as if I am complaining or anything. I really do enjoy this game and think you guys are doing a great job.
