well why not make a useless weapon more effective?

Let me explain myself first.

Dust is like a role playing game, and a first person shooter. I've had experience with both.

Every game developer wants to have that meatshield class (heavy dropsuit)

Every game developer also wants a DD(damage dealer) (heavy dropsuit)

You can't have a dropsuit that has the most damage and the most health/armor/shield (whatever you call it here) it ruins the game. Like I said at the title, if you have one class that has the most damage and the most health is going to lead to a massive influx into that dropsuit. The logical answer is to give Sniper rifles more penetrating damage.

Sniper rifles should have more damage because first off you dont have a lot of ammo, you can't use it in close quarters EFFECTIVELY, and it is infact, a sniper rifle.

The lack of ammunition gives a good reason to give it a boost in damage to deal with heavies because if you miss, the heavy will notice a bullet just zipped by them, and will run into cover and then dissapear out of sight.

You can't really use a sniper rifle in close quarters, it takes more than one bullet to kill something, unless you're using a charge rifle which is still innefective because you have to charge it and by the time you charge it you're in the spawn screen. So there is little to no quickscoping in this game (which I like).

Sure you can pack a smg in your pocket but still you're going to get killed because of the lack of damage.
Also the sniper rifles need to be a little more useful, I mean c'mon lets stop this b.s. with the heavy lovers saying "hey dude, why dont you run off to your teammates and bring a few guys then, and only then will you be able to stop me" there needs to be weapon balancing, you can't have 5guys trying to kill one heavy, because like I've said before. What if there is a whole team of heavies? does your team instantly get 5x members on your team?

I just want to hear why this would/wouldn't be, a good idea for a nerf/buff to heavies. I know this will effect other classes but then again, other classes are much faster and can dodge bullets unless they stand still (a tip from me. never stand still for more than 3 seconds, and never go back to the same spot until 10seconds go by, people get impatient, or think you've left).
