In game this fast paced, FFA is a must. Hope it will be brought on very soon.
Also, I see here that everyone is strongly against so called "kill trading". I think all of you are wrong. I played warface for a long time, and thats the one thing that pissed me up the most, vanishing of the last shot fired. You take a shoot simultaneously as the enemy, game decides that he was the first one taking the shot, and boom youre dead, and the enemy jumps away happily. Considering the ping differences and net code, I think its safe to say that some randomness is occurring, so the kill trading is a nice feature.
For the sake of realism (fast paced FPS realism ) please keep that kill trading feature.
