Uninstalled today. I like to play co-op and it is absolutely useless in this game. Funny, since it works beautifully in BTD5. But in BTD6, it's constantly lagging, dropping connections (despite having great internet) and it will boot you out asking you to "rejoin". Only to have you click "rejoin", wait until the end of the current round then go through the loop all over. So you get through many levels only to get locked out for no reason. For a multi-million dollar company, you think they'd hire programmers who ACTUALLY KNOW HOW TO DO THEIR JOBS.
