I think you should inspired of the "best" physical mech by clevername ( the build you see can possible is not the "exact" build )
- You don't need probably the teleporter, you have a grappling, charge and the distance shreeder who inflict expensive damage .
- have you a matrix or maximum protector or something like that ? it will always be better than having only one resistor
- Have hight hp is good, but have effecient heat and energy stats is better, maybe remove 1 or 2 platinium plate and replace it by a energy and/or heat module ( you have double module ? )
- Have you a seraph blade, a mercy, a annhilation or such a weapons ? use 2 rock polisher is ..not really advise for your Hp [ and also a mech with 4000 hp without resistance resists less well than a mech with 2800 hp with resist ( often ) ]
Also the drone is Ok, is not best but is not worst ( the protector will be probably the best drone or gardian if you have it or even tonto if you use a mercy or rock recoiler ),
I could be wrong
