Guess I'll just throw my 2 cents in here as I've been playing nothing but warpath recently, and it's growing on me. Warpath -needs- sudden death, it's just par for the course with a map like this. Every time it ends in a stalemate I hear groans at the lack of a way to end it aside from stalemates, and it also results in at least 1-3 people leaving the server each time.
One of the problems with sudden death on warpath is that players are reluctant to leave bases on regular sudden death, where you have sentries and ubers. The solution is to remove that, by making it a random class melee sudden death. 90% of the rounds will end with closure, the ones that don't will be because someone is sneaky enough to avoid being killed. Wich itself can provide some enjoyment, situations like this often have hillarious results.
