AI is too easy, more difficulty options plz

I'm pretty sure that most players forget about Coop vs AI after reaching 30... But I'm one of the few who really enjoys playing Coop vs AI mode. I like trying out new champs, fun (=troll) item builds and taking it slow and easy - you know, without the stress/fear of getting bad-mouthed or ridiculed by other players. Lack of player toxicity is one of the strong charms of playing vs AI.

However, currently the AI is so easy that it ruins the fun. Most AI champs are:

Weak - No runes, no masteries, no summoner spells.. not on even footing with the players. Dumb - Dumb path-finding behavior (First blood exploit using Towers), Ryze bot trying to Q you but getting minion blocked, etc Have weird item builds Lack objectives - Bots will never take down Dragon/Baron No Jungle - Bots will always duo top instead Lack of bot diversity - When will I ever see Zed/Ahri bots?

Could we get something more challenging than 'Intermediate' please Riot? As much as I want to enjoy vs AI, there is no fun when all 5 players are roflstomping (double digit kills) and breaking enemy Nexus at 15 min mark.
