Voidghost reminds me of ravana from war robots. Multi-use ability which makes it invulnerable for a few seconds on each use. I can see why war robots no longer lets weapons lock into dumping their magazines the moment you click. The only one like that ravana could ever use was talumbas which wasn't very strong however war robots also has an active module which mimics the ability so you could attach it to any robot. Put on something powerful that's fire and forget like pinata before the rework and you'd get something happening like what's happening with voidghost.
But getting rid of the fire and forget doesn't solve the problem either. Ravana in war robots is still able fire its weapons then use its ability to avoid damage while it reloads gradually reloading weapons.
I said it this mech is broken by design. It can either be unusable or it can be broken. There isn't an inbetween. And it's looking to lean more towards broken.
