I enjoy using this mech as a Assault support, is a great light mech killer and tends to lay down some extra hurt with bigger mechs as they normally ignore it. I am not a big fan of using XL engines unless absolutely needed. In this case you can drop in a XL180 and add another ton of ammo, armor, or even JJ.
Due to the fact LBX is the main weapon, it generate low heat and requires to brawl, you can downgrade to SHS and fit a bigger LFE for increased speed.
Yep, this was mostly made as an experiment, it has since been adjusted to a LBX-5 and 3ML. Works much better.
