Just an idea I thought up of today. Whenever a pro is killed in a certain way, an animation for being head-shotted, burned, slammed, ran over, etc. will happen. It would be neat to see each pro reaction differently to each death.
Or you can taunt while you're dead. "Ha ha, I hate what I do". "When these fists talk, I'm dead". "The water that support's the Jet Skiiiii, is the same that engulfs it". That last one works both ways.
But I love ragdolls, especially the ones that keep momentum, faceplant and skid for a while and coming to rest at your feet.
TF2 did something like that. You'd backstab them or headshot them, a little animation would occur about 50 percent of the time, if it didn't occur they'd just ragdoll, and if they did occur, the animation would play out, THEN they would ragdoll. It was funny.
