Casual MAD-4HP "Great Wall of Texas" (2xMRM40, 2xLRM15, 4xERSL, LE300)

Slow, underfunded, head slot is empty - but it can put out a big punch.

Use LRMs while waddling up to lure in mechs.

Alpha all the missiles to help combat AMS.

 

This is actually kinda brilliant on paper. with an optimal range of 210-500 but still fairly effective at 0-1000. the only issue is slot and ammo management.

 

Probably plays well on table top.

There might be better mechs for this type of build.
