The zm needs to adjust the amount of time a zombie could be on fire when hit by a grenade; it's just too much at times. With fewer people on and a few zombies, a 38 second grenade fire time will really slow a zombie down and ruin the game-play by making a normal zombie useless.

What the zm needs is Nade fire be based on the amount of players.

1 zombie = max of 8 seconds
2 zombies = 9 seconds
10 zombies = 20 seconds...

and capped it off at 25/30 seconds.

This is just an idea; I just would like to see if others feel nades are too long or if their just right.
