If you go unarmed to use predator's stance, you'll get seriously hurt on civilized cause
you can't parry and your dodge will take a hit, any competent group of 2+ will eat you alive.

So assuming you wield spear for parry, what is your strategy for serious hurt?
Dervish dance? It's pretty much shit. 1 good hit and damage scaling on subsequent ones.
(You need edge and they need to be blind for 3rd hit IIRC)

You'll also be bashed down to death.

If I *had* to play a civ ranger build geared for raids, I'd probably play hunter.
