Newbie question, regarding the SS Nimble Tank Assault RifleBuild. how do I play both nimble and a tank? Or do I start as a tank and then switch to nimble? I see you chose juggernaut at level 12, so how does it work with nimble? I'm guessing Armor Sloping might be involved, but I don't know how it works, what body gear should I use in this build ?
