Things that I am seeing more often then not:
Campaign multi seems to not use trueskill at all or at least feels like it, I think 90% of my story matches have been huge steamroll losses (with me in top 2) and it's annoying as shit.
Whatever trueskill is going on doesn't seem to be strong enough, I had a bunch of matches tonight where three players on the enemy side were all gen 2 while I was on a team with average level players and it was obvious that the skills were stacked, would help of my team tried to cap points, too.
In the beta I loved using the carbine but here in retail a lot of these maps I am just running around spraying the smg with good effect, maybe they did some re-balancing?
There is little use of most of the structures on a lot of maps when you can just run across them, the game is too fast paced to hide well in a room unless you have to because of capture points, and then those are in medium sized rooms with more then one entrance.
Low ping EU servers seem to have a lot of small hickups for me which were not in the beta, players rubber band or skip around, at one point I honestly had sub 10 fps for about 3 seconds, caught it on the game DVR.
I dunno, the game is just rubbing me the wrong way right now and i'm not enjoying it as much as I was expecting, I had some hype for this game but not enough to be above realistic expectations.
