Honestly, I'm OK with him doing that much damage. I like the idea of taking down two or more enemy demigods in a handful of seconds - it makes you plan different strategies.
In this beta release, I don't seem to have the crossbow guy, but I've found him to be very effective against unclean. He can lay several damaging mines, plus scatter a few anti-demigod mines for his retreat. Rook is very effective against him, too - he can stun him with a bowling ball, then hammer him into the ground like a tent stake. But you have to choose your abilities to be anti-unclean if you want to be effective against him, and plan your attacks and strategy accordingly. He has his weaknesses.
Is there a way we can all play this online? I'd like to test the strategies I've developed against other players
