I'm glad I'm not the only one to have had this issue with BC:2. It really spoiled the game for me. I played as medic but still got most of my points from capturing bases. The amount of people who seemed happy enough just sitting in one spot getting 1 kill every 5 minutes astounded me.
Hardly anyone seemed to want to go for any kind of objective. I know there was that mode where you push into the enemy base and admittedly everyone usually followed that, but I didn't enjoy that mode as much as the traditional catch all the bases style of game.
My favourite games of the series have been: BF1942, BF1943 and BF2142... it seems battlefield games have only really been good when there's been a date in the title. However, I am going to be following this release closely to see if it'll be worth getting.
