Nice for running through the enemy lines in mid- to endgame and dismantling everyone in your way. Can also chase mediums and some lights .
You got Speed! But you dont have the Firepower! LBX needs some more secondary Weapons to peel off Armor, before becoming deadly. Besides, what do you do, if you lose your Arms? And why the hell dont you use Double Heat Sinks??? How about this:
I currently run that build on my Firebrand Blagg. You could have 6 MLs, but I prefer 4 so that I don't have to worry about heat so much. The LBXs are vicious
I use a variant for the dual LB10. 6x spl to fire with no break in close range with an xl 280 ansd 13 DHS to put everything this beauty need
