I gotta say, blues are definitely awesome. My corp was farming green mechs the other day, and we had about 6 - 8 combat peeps. One of them was in a yellow mech, the rest in an assortment of green and blue lights and assaults. I was out DPSing the mech (and for that matter, everyone else) in my blue arbalest using UDC rounds. I can't wait to see what a kain is capable of with gauss guns
