As stated, third person views for Mechs will not be available in our Release, these are merely our Debug Views for development and testing purposes.
A couple reasons we didn't incorporate third-person views is because it severely undermines the specific advantages that Battlearmor have, like not being seen on Radar, not being seen under the legs of mechs.
Also, we have a distaste for third-person in regards to the "MicroMachine" feeling it gives you, as stated by Kami. It makes the mechs feel less like simluated, multi-meter machines of war and more like toys with a god camera.
As if those two reasons weren't pervasive enough, it also takes away from people's ability to manipulate the environment in ways which they would not be able to from within the cockpit. Seeing over ridges, from behind buildings, and so forth.
I know it's a scary thought for some, but you might actually have to SEE your enemy face to face to fight them, rather than get the jump on them from a safe position with an altered perspective.
