I think the Guardian should stop firing or stagger when we hit it with a heavy melee, and that the guardian attacks need to be unparryable.
Right now, the attackers don't take enough risk when trying to slow or push the Guardian. If the Guardian's heavy melee couldn't be parried, the attacking team would actually have to put themselves in danger to push it, giving the defenders a fair chance to counter by parrying the attacker's heavy melee.
It just seems more balanced this way. I've had way too many matches where I'm forced to just stand around helplessly while the enemy easily parries the Guardian and gets a free push.
