Nope,that’s not possible.
I have a mech with 3 weapons,2 heat engines,1 cooling booster,charge,hook,void and 5 plates.
2339 hp,500+ heat,250+ cooling and no energy.
It’s not weight,it’s called “using your brain”.
And no,It’s not that easy.
For such a build you’d need many premium items.
Not the weight is the problem here.
