New game mode specifically for training/honing skills

I think Riot should create a game mode specifically tailored for training/honing skills. At the moment we have bot games but I don't believe this is going far enough. While bots are good punching bags to test out champions and abilities, they have a limited scope of what they can or will do, and there are limitations to what you can practice. I think there is untapped demand in the community for a mode where you can remove all ability cooldowns, choose exactly what you want the AI to do at a given movement from 50-100's of options in-game, have infinite gold to buy items...etc.

A mode like this would allow people to practice all types of scenarios, practice skills over and over without being hindered by ability cooldowns, and test how to counter certain strategies or actions taken by AI on the map (can practice stealing baron or dragon for instance). This mode can be a custom type game mode only available in the custom section, or it can an extension of battle training of sorts.

Let me know what you guys think and upvote if you like the idea! A reply from a Rioter would be a bonus ;-).
