A worse version of @SniperCzar 's Valar Morghulis. Takes the alpha strike to a new level. Gauss rifles hit one component, open it up, LBX20 follow to instantly crit/destroy the open components.
I agree with epikt. Too low on ammo. How about replacing one of the superheavy LBX20 by a set of quad Wubs with similar crit chance and making the build less ammo-dependent? Add a TC1 and it looks like super duper killer.
NOPE NO COMPROMISE ahaha, see title. It's a joke build, yes it runs out of ammo, but you simply aim toward the enemy, perhaps make a flank manuever, and kill as much as possible before going down. It's a suicide mech most games. It has enough ammo to easily kill 6 mechs and score just under 1k after crits, even higher if you're lucky.
Its more about the fear of being made into mince meat, I suppose the lbx 20 could be gauss rifles or uac20s but I like the thought of 60 projectiles obliterating any medium or light that happens to cross me.
