I feel like this could be achieve with different parts.
See with this build, I can pack on either more HP, more energy, more protection, or another weapon. While maintaining pretty damn good stats.
I also did some number checks with your builds…
Energy total is 334 with a 154 regen total.
Heat is 371 with 211 cooling.
And a total of 1988 hp with four plates + iron boots.
Mine, which is
371 energy with a 148 regen total.
490 heat with 259 cooling.
And a total of 2049 HP with 3 plates + iron boots.
I’m not trashing on your build. I actually quite like it, just not really maxed maxed for me. I do love seeing these creative builds though. Since mine, obviously isn’t custom at all.
