Ok now that most of you have tried this mod, it's time to ask this again...
I played crowded LT yesterday (I think 5vs5 or 5vs4) and the game SUCKED!!
Now that the friendly fire is on you can spam as much as you want... The game was full of spam, I got killed by grenades and rockets only (70% grenade spam 30% rockets).
I loved the fact that you had to be cautious in team matches if you wanted to spam (when there was no friendly fire)... Now you don't have to care about that.
