BFBC2 had its own problem - retards that went for kills instead of objectives - while cod was full of them too - they actually did something useful - in bc2 it was common to have full team of camping recons... while being on offense in rush.

Buff - in domination in mw2 you needed to think actually - not in each firefight, but generally you wanted to box enemies on one point in line-setup( A B C points set up in line - ie you have to get A then B if you want to get C), or rotate the points in triangle-setup( you can go from each point to the any other point in this one). And never ever let your team grab all 3 points.
