WHK-B "The Cleaner" (2x cLRM15, 1x cLRM10, 3x cERML, 1x C-LBX5, cAP, cTAG)

Simple, brutal, effective. Slam the LRMs till opposing forces are yellow and red, then move into brawl and clean up. TAG can get exchanged for a fourth cERML, ammo can get reduced for Artemis in exchange. It is just mean that you got full armor and some brawl weapons in mid- to endgame, as it oftenly is the plus your team needs for a win. I confess, in premade 12er matches it would not be of that use it is in PUG matches. But for me it is pure fun atm, was my first Clan mech I mastered.
