The first wave has no weapons, at least give them butcher knife or wooden club. Add a samurai wave with katana, bows, nodachi. Or ninja wave.
The bots spam too much and my ping is high, hard kill them without tactical positions.
I do like the idea of players taking control of bot when died, makes it harder and unpredictable. You don't know the one you fighting is bot or a person. But then again, when fighting for both sides, the xp + gold rewards are mess up.
