I don't know why you vote for FF on.
Tremulous isn't an FPS like any others, where you die, and say 'Oh well, our team is now smaller, and the foe earned a frag'.
When you die in Trem, you help the other team with one frag, ok, but you help them to reach a Stage earlier. Also, you help the player who killed you with credits/evo points.
My opinion is that too many players don't give a thought about how dying affects their and the enemy's team's chances and success for winning. It's a great responsibility.
So if you buy a Luci and a BS for example, and a kind teammate shoots you in the back (no matter if it was an accident or not), then you die from a Dretchbite. You lose your equ. and money, you weaken your team (because you won't have money for another armor or a weapon for example, so you are an easy kill), give the Dretch an evo. point, give their team a boost to reach the next Stage, so you made their team stronger.
