I would suggest taking that MPL out of the arm and putting it in the head and put the extra 1/2 ton AMS ammo in the legs. or ditch the half and go full armor on legs/arms/head as well. Use the empty arm for shielding. Just my 2 cents
You're right, the head is a better place for the arm MPL...don't know why I did it that way, likely to try to use the arm flex. I updated it and tweaked the armor. I've burned through 2.5 tons ammo with 2xAMS several times, that's effectively only 1.25 tons ammo since they shoot together.
Yeah I've had matches where I burn through 4k AMS ammo in no time. Then I've had other matches where I barely touch 1k lol Edit: also, if you want the arm reflex for weapons, you could take the 2 CT MPLs, put one in each arm, and the LPL in the CT. Just a though. All comes down to preference.
