That's not OK. How can it be that an attacker is wiped and still wins the round?
In the actual system, it is.
Why ? Because winning a round doesn't mean you are winning the battle against the players. You ONLY needs to defeat the PNJ waves one by one. There is NO needs to even fights the others players (just heal yourself watch the PNJ and go). Yes this is making the fight for small OPs ridiculous.
