Ah ok. WS was the first one I got. I guess it depends on which path you took down the skill tree (I think I remember you saying you were a Human Comm?), I followed the Cyber Comm guide on here (loosely) and went the Smoothbore battlecry. It was useful for Everlasting Hate as I could keep all the melee goblins at bay whilst wittling away at the trolls armor.
And yeh greed will get you killed in Ice Forest, distance is king for the commando. The only time I jump into the middle of a pack (when not forced to by the jump pads) is when I am going to unleash a ruiner or sentient weapon.
The pain, the torment and torture, profanity, nausea, suffering, perversion, calamity. You can't get away.
