I guess I don't understand the issue with having suicide stand as it is. First, just as with anything it takes thought to do it. Yes I have a bind, but I made the choice to do that. I have to remember to do it when I screw up an attack. Many times, despite hitting my bind key, I still get killed and the survivor gets the point. I see this as an opportunity for someone thinking fast to deny a point or two from the survivors.
If we are going to change it, ask yourself why. Is the ability to suicide really throwing off team balance that much? This is the very first time I have heard anyone complain about suicides at all.
