Tbh, that is one of the worst combination I've seen so far.
Lava feet on an energy mech and no range one weapon, they'd have to stomp, which is heat based, doesn't help the energy focused mech. Res drainer? Sure, it might work. Sniper builds without the three weapons (e.x. rock recoiler, ejection blast, and dark eagle) are easily counterable by close range mechs.
But in this case your mech is not so good, so there's that.
