oh for... DO YOU KNOW HOW TO READ???

Start here.

You seem to misunderstand what Are denial Weapons are.

en.wikipedia.org/wiki/Area_denial_weapon

You also need to reread the Mass Driver Weapon description.

You want the Heavy, to be shoe horned into a role you think it is meant to be. You should also reread the Sentinel description.

So I have a serious question, and this is not intended to come off in a snide tone.

But in over six months, there have been no less than five serious, well thought threads on addressing HMG dominance in CQC. There has not been a single dev response, nor any indication that these threads have even been reviewed.

In fact there has never been a non-trolling dev response in any similar thread in two years that I have read.

Why?

Further, Sentinels/heavies have been proven more problematic than worthwhile in a balance perspective, so the answer has been "make them even MORE CQC. More of the same thing that has never worked should work now, right?"

Why are Heavies not being repurposed to dedicated AV and area denial?

Area denial is not room by room brawling. Area denial is what you post at the door/gate to keep people OUT of the rooms in the first place.

Sentinel suit's advantages and disatvantages are TEXTBOOK examples of open-ground, area suppression parameters. But they are being crammed into close quarters.

Why?

The only answer anyone has EVER provided is "heavies are cqc." This is a non-answer that holds as much validity as when I say "because :reasons:"

There is no vision for the heavy suit. They were originally billed as the go-to suits for AV and area denial. What we have is a CQC brawler that performs poorly in an AV capacity compared to lighter, more agile AV options (swarms).

So instead of doing more of the same thing, why do we not separate the role of the heavy, which should be a support platform that assists an assault squad, from the assault, which should be the go-to suit for attacking in CQC?

Actually Historically speaking Heavy Armored Soldiers Trump Lightly armored Soldiers in CQC, but lighter armored people can skirmish harder.

Heavy Personal Armor came about due to close quarters combat after all.

That is what we did, During Vitamin the US would use M48s and M60s in urban environments, these tanks were small compared to the MBT of today but we would trounce them in hot urban environments with infantry support to provide Firepower and wall busting to take out entrenched snipers and machine guns nest.

You telling me if we had a man sized heavily armored suit of Powered Armour armed with a LMG we'd not use it for Urban Fighting in buildings and out of?

A Man Sized Tank that can move faster than normal men while holding normal weaponry would not be used for breach and clear?

The US Navy and Marines think otherwise.

Whoops not the M60 but the M103, I can't recall if any M60s were fielded in Vietnam other than bridgers and recavs.

IMHO, I think the focus on the HMG rebalance needs to be its range. I think any PC player (or any seasoned vet) understands that if you run at a heavy full-frontal, you will lose. However, on numerous occasions I have have placed myself at reasonable distance and still I have been shredded down. The HMG's reach is just too much for the sockets we're playing in.

As for the Heavies role, I am pretty sure it has been established that they're PtD (Point Defence).

Dust 514 is a Class Based shooter with all 4 of the Traditional Classes with some mix and matching, the reason the Sentinel is a High Damage Bullet Sponges is because that is what the Role is traditionally, High DPS, High Health, Slow mover.

It is just a design choice on CCPs.
