So about those bot bans

So just now, I decided to play a 3v3 game with my friend who is new to the game. We got into the game and went bottom lane, and a trynd comes out of nowhere and walks into our tower giving us first blood. At that moment I knew at least he was a bot. But then their Ashe kept going into the same bush over and over again, and their morde would mindlessly suicide at towers and push, just like our cho. I played a 3v3, and were it not for me and my friend, it literally would've been 6 bots against each other. No wonder the queue time isn't 20 minutes, (It was only 1:40, which gives you an idea of how many bots there are, considering even the draft pick queue time is longer than that.) However I did find it interesting that only 1 of the 4 bots had been updated to recognize that there are now 3 turrets in each lane of TT. I know that botting has always been a problem, but I've never had a game with more than 2 bots in it. I feel like the problem is only getting worse.
