i like the sound of the 10 points thing for perks, especially since i often used to play knife only (which was actually challenging before comando etc bullshit).
i also like the sound of competitive ranked mode, but would much prefer it if it was search and destroy, that was were the real competitive scene was for cod4. team death match will never be a tactical/competitive gamemode and 4v4 feels too small. (6v6 doesn't count as killstreaks completely retarded). 8v8 s&d ranked with no killstreaks, would buy the game for that alone.
but still no dedicated servers = no purchase of cod from me since cod 4. if they made the games better every year instead of continually worse, id be a sucker just like every other retard who buys these games.
