Played it recently. It wasnt too bad, but well... boring. Nothing you do changes anything. It didnt matter what flag I captured, what tank I destroyed or how many I killed, they'd be back in 10 seconds anyway, and the flag would go as soon as some random lone wolf sniper/spec ops/medic with uber G36E that he has though his army doesnt support this weapon appears at the flag, jumping out of a blackhawk that he lets crash into the next hill, para's down on the flag and waits for like 20 seconds, and the flag is taken again. Then he leaves, and as soon as he does the flag is full of artillery spam.
Taking flags isnt fun either. You approach, maybe even stealthy, but as soon as you're there its usualy no enemy anywhere around it, or you get arty- nade- and god-knows-what-else-spammed due to an all-seeing commander putting a holy UAV into the air over the flag. And if you're lucky and there's noone, you'll get arty'd as soon as you cap it. Unless you run away fast enough. And if there actually are enemies, you may shoot them, but they'll spawn right on top of you again before you can capture the damn flag.
Medics don't care about anything, just throw their bags around so that sometimes maybe one runs over them so they get score. But, who needs medics anyway? Why not just wait 10 seconds, you can respawn anywhere on the map anyways.
Nothing you do matters. At the end its just a hunt for score. Largest e-penis wins. (Had most teamwork points, member of best squad and best in nearly every supportive class btw

... Yes, it was just a score hunt.)
