Until about level 10 I loved this game, I played it for hours every day for a couple of weeks. My win:loss ratio was about 1.6, and I actually consider myself an extremely fast learner, still a ton more to learn though.
But now it's just not fun anymore, my win:loss ratio is down at around 1.1 now, I lose every 5 of 6 games, yet i'm MVP. I absolutely dominate the majority of my games, but my teammates (I assume due to (admittedly, must be very good) matchmaking) are just, absolute nightmares, I constantly get people with 0 kills and 10 deaths, feeders. I had a game where I was 30/1 and we still lost, yeah, and that was defending, I wasn't hiding. These teammates are driving me nuts, the game actually isn't fun because of this.
Anyway, sorry, the rant seems a bit pointless because there is probably nothing that can be done about it, boosting 3 (sometimes even 4) players is too hard most of the time, but I've boosted 4 idiot teammates to a win many times.
