Pyromaniacs in Highwayman Hills!

The Pyros from Highwayman Hills are doing TOO much damage. Also, they attack randomly, not caring about agro whatsoever. And they usually 1-shot everyone but the tank, wiping the whole party. Which is not really fair... We can fight 4-6 swordsmen and 2 snipers at once without issues, but once we get 1 pyro we get wiped...
