An annihilation, nightfall, night eagle, with the void drone, is one of the most popular high level physical builds right now, plus you have a leg/myth charge which is useful for that build. This is probably your most complete build with what you got, your void drone is already max legendary, and the brutality is decent for this build (Would also be decent for energy build but there is better for both). Ditch the back breaker, level up the annihilation.
Either way you are going to need some more plates and modules unfortunately.
Since you do have the energy shotgun and legendary energy hook, plus face shocker, you will ultimately be able to make a nice energy mech, but you probably still need at least a last words, I don’t know you might could cobble something together, but like I said I frequently see people rank 2-3 using an annihilation, nightfall, and night eagle with the legendary charge and void drone. Get the right modules, more plates, and another annihilation, and a build like that could take you to the top.
Also I have a maxed face shocker and a maxed windforge, and I find myself using the windforge, face shocker is decent but once you face higher HP enemies it is gonna run out way too early most times… I go back and forth though
