So,that would be a physical type mech,huh?
First of all,you should improve your max heat and cooling
Second of all,a little bit of extra hp wouldn’t hurt anyone
As for the third…Physical types mostly use energy-free weapons as side weapons.That means energy isn’t really that important for them.I’d go for some more cooling instead and why not replace the backbreaker with a second annihilation if you get one?
(Energy-free,better range than the hammer,drains resistance)
overall,I’d give it a 6.5.You pass,tho you could make a lotta upgrades and changes
