Most meat heads either want to kill stuff, kill stuff on hardcore, or Search and Destroy (because you can show off how "ownage" you are).
When it comes to objective based gameplay, a vast majority of the game wont play it. (See Search; how many people do you know will HONESTLY try to arm the bomb...?). Its the "Meat Head" demographic, as I call them, that enjoy and play those types of game lists.
To Infinity Ward; its either keep another server up that people arent fond of, or change that server in an attempt to get more people to it (giving them reason to keep it open).
On a side note, I would like to add a =(, Flag is almost ALWAYS my favorite.
On a troll note; I would like to add that TF2 and Halo: CE (the original) had the best CTF of all time! Of all time!
