I agree with the hardcore mode...except I suck at it.
In COD, my KD is normally above a 3/1. In Combat Arms, my K/D is around 2/1.
In AA, my K/D is 0/4 on average.
*sigh* It's simply not my game. I love it like a younger brother and I played it since 2.6.....but it's simply beyond my comprehension. I quit playing after I got banned by punkbuster for disabling some security measure. I didn't feel like going through Special Forces training again.
Hardest, most pointless mission in the history of games known to the American Man.
