I know there has been quite a bit of talk about how the tech is op plz n3rf and all of that, so what if the devs just tweak how armor works? Here's what I'm getting at: Suppose each mech body is split up into limbs and torso, and each has their own health bar? Then the tech would have to be more precice with what he he heals.
You could even make it so that once a part is heavily damaged it starts becoming slightly dysfuctional, like if one of the legs were damaged move speed forward and backward would be slightly decreased, as well as strafing to the side that the damaged limb is on. Of course you would have to make it so that it's only up close that you can see the remaining armor of all the limbs of another teammate, otherwise the HUD would be too crowded.
