It's a great brawler, and thats all well and good, but seriously I think its way past time for an arm extended sniping mode.
It would also be pretty ******* simple to balance.
How would it work? Simple.
Press a button and your left or right arm extends straight out in front of you.
When in this mode your mech can only move half speed, and when you do move you get reticle shake as long as you're on the throttle.
Boom, suddenly the black knight has a reason to toss some large lasers or PPC's in the arm.
I'm sure it can be animated to not look completly stupid, I dunno give them some kind of stance

MECHS HAVE ARMS, stop being lazy PGI.
