Well, they done ballz up the MM for Co-Op. Random, I can somewhat understand. If your Kawachi is CONSTANTLY getting into matches with T5-6 things, then I can see it being a problem. Every now and again however, just added spice. However, it really messed it up for the Co-Op side of things. In Co-Op, it doesn't really matter. Hell, I had a match with my Fuso that had a Midway. I thought it a blast and made good xp for a Co-Op match, specially since I caught that AI Midway out by it's lonesome and sank her.
Now to dink around with my Mogami, I either have to chance being in a match with mostly AI on our team, or stick to my premium's. Their MM is different.
Should've left MM the way it was for Co-Op.
Oh well. I figure I'll start a topic over there about it later, after I've put in a little more time. It is possibly, though unlikely, that it was due to the time I played the matches, which was around 11pm central. Around that time during the weekday, numbers for Co-Op are not solid.
