Pistoleer Archive

well i have been working on the grips and stances tier of pistoleer and im nearly to stopping shot but im not doing it for the stopping shot im doing it for thetier for the stun/dizzy/knockdown/force changed stance defenses. How are these defenses really working? I want these abilities so i will be able to stay standing up long enough to get a monster shot off with my special heavy weapon...

basically im asking am i wasting my time with pistoleer? will i be just as vulnerable as a regular old commando?
