Us heavy users are supposed to be able to take on a freaking tank! Make it reflect that, make the cost of our equipment higher and in return give us our lead-spraying mini-guns, our armor that makes it that we aren't dead in seconds. When people see a heavy dropsuit jump fall from the sky, they should be running like hell, not laugh. Also, the default heavy class is unplayable against infantry, the pistol does not suffice damage-wise.

Maybe a Heavy Laser Weapon is coming? That would be awesome!

Heavies never asked for OP suit or gun we just need a reasonable gun we can fight with, i agree heavies shouldn't fire bullets without limit and hence the overheating but its broken at the moment. Let me give you a situation all heavies with HMG encounter and hates:
Am as a heavy in a fight vs assault/scout in CQC we are hitting each other he starts to straf my bullets start to scatter as i struggle following him because of the turning speed but still i manage to drop his shield and most of his armor and just before i kill him my HMG overheat and stop! he reloads and finish me off as he pulls back away from my killzone, this has been the scenario in countless encounter in this build.
The gun overheat before it can deliver a reasonable amount damage and that due to heavily reduced bullets damage adding the slow turning speed of the heavy dropsuit all this rendered the heavy class useless/worthless.

I do switch to my Sidearm but sometimes its too late (current weapon switch is slow) not to mention my Sidearm is too weak to compete against upgraded AR or SMG because i spend million of SP on my HMG which suppose to kill the guy without needing my Sidearm.
You must be unlucky guy if you are being killed a lot by heavies, a piece of advice from a heavy user: Don't ever stay still in front of a heavy try to move left and right all the time or get behind him.

I personally suggest an increase in DPS for the HMG to where it outperforms every other weapon in close range while remaining very bad at long range (due to the reticule having to close) and lackluster at medium. Unless the HMG is king at close range, it does not have a purpose in your game.

A shotgun is a X2 skill not a X3 and uses X2 supports, costs less ISk, and you can mount it on a scout or assault and not the ever-so-slow heavy. A heavy can't turn fast so a shotty would still be superior in super-close range. I'm talking about short range like 5-10 meters or so, not in your face stuff.
