It is my belief that deserters of the front need to be disposed of in the appropriate way, FF would enable this. anyone remember that game with me yelling trough the mic "NO MAN BEHIND ME, NO MAN BEHIND ME, FOR THE MOTHERLAND WE IGNORE THE PAIN, THE BLOOD THE MUD ANY MAN BEHIND ME WILL BE SHOT TAKE MY WARNING IGNORE WHAT IS IN FRONT OF YOUR EYES A NEW CHARGE DAWNING MOVE FORWARD MEN, FORWARD TO GLORY FOR STALINGRAD FOR STALINGRAD DESERTERS WILL BE SHOT FOR STALINGRAD" STALINGRAD! STALINGRAD! we won that game (i think, at the very least we kicked butt), even thou we were heavily out gunned and had only 1/3 of the rez nodes, but we kept breaking the imperial lines and once we broke trough we charged to there commander and did some in base damage our commander personally thanked me for the motivational boost don't remember who it was thou, if someone recognizes the scenario post plz
FF will make nukes obsolete, thus rails and HE are the supreme tank weapon, thus NF heavy will stand no chance vs BE heavy.
Left4dead doesn't make it fun though, the FF is one of the worst parts of left4dead, especially when one idiot with a shotgun can ruin a whole team's chance of winning.
I actually like the FF in l4d. Same with Insurgency. In both cases it adds another level of challenge (i.e. no more spray and pray, you have to actually AIM). However, it would be a disaster in Empires because of the numerous vehicles, explosive weapons, etc. that would ensure many unintended TKs. For FF to work, you really have to design the mod around it.
