Firewalker deals an incredible amount of damage through his AoE and it clearly outweighs his cost, but oh well damage and cost, he gets positions. Why solo sniper in cloak doesn't do the same remains a mystery, let's say I build sniper but it doesn't pay off.
I tried to kill the firewalker and two attempts failed. I don't get the hell why moderators and puppies are AA, what the hell? Let the firewalker spend 550 mettal on AA.
