Yeah, LoL certainly did have it's cesspool period. A couple weeks and dozens of bot games, ARAMs, and blind queues though, and I've only seen one jerk. I'm kind of blown away by that.
I didn't know that they put a requisite human count in the botgames, though; That seems reasonable for reducing stress on the servers, especially for a game that's meant to be purely a multiplayer experience- but those singleplayer VS bot games had a lot of functionality for destressing, testing new champions or item builds without having to worry about other humans you didn't trust berating and/or interfering with your warmups.
I'm glad that dipping my toe back in turned out so well.
