where is the line drawn?

by all means this is not a rant. just a question. when i first played crossfire i was informed it was a game of steel,blood,and skill. after some time i realized there were different versions of crossfire that were more advanced. i seen the barret. so i went to the forums to ask for it but then saw a post that said not to ask for it,the post said crossfire was not a sci-fi shooter. soon after that post mutation mode was released along with the crystal m4.not to mention ghost mode that was already released. so now i ask. i can look at crossfire korea and pretty much find out anything that will be coming to our version. you didnt add the barret but you did add the crystal. where is the line drawn between sci-fi and blood and steel?
