If blitzing was too cheap, everyone would do it yeah.... This would effectively lower the skill requirements of the game. Blitzing used to be 1 coin when it first come out (provided your damage was low enough). I loved it as I blitzed out whole events as I am certainly happy to spend a coin per target.. Then it rather rapidly creeped up. If you want to blitz an event I think it should come at a price though.
