Co-op vs. AI is Broken
I just got out of an intermediate co-op versus AI match, as I was just messing around on an alternate account of mine. However, the co-op versus AI option is broken. Not the link, but the game mode itself is broken. In my most recent match, all four of my teammates were bots (and every co-op versus AI match I've been in recently has had at least one). For someone who's played for a long time like myself, it's not a big deal. For newer League of Legends players who are still learning the basics, it's intolerable.
A newer player won't enjoy the challenge of having to defend against five fed enemy AI when they're around the level of skill of the bots anyways. If you have four bots on a team that all run down mid and feed the AI Katarina ten kills in ten minutes, they're not going to enjoy getting one-shot by her. They're not going to be able to handle extreme ramp up in difficulty (unless they're already far above the skill level of the AI already, but this isn't about those people). They're not going to have fun, and then they're going to quit League of Legends.
It's ridiculous that mode in which newer players are supposed to be able to learn, practice, and experiment on is now broken beyond belief. There's no sense of competition against the AI - unless you have at least one player on your team far above the skill of the AI, if you're a beginner, you're destined to lose because of the bots.
And also, from the perspective of someone who has raised the level of his accounts on his own, it's despicable that people can just buy botted up accounts and not have to earn anything.
