OK, Heavies are fine to the average VET
I have not had too much additional troubles pwn'in faces as before uprising.
EXCEPT the stupid slow turning speed. Now when scouts get in my face I **** my pants as I try to keep up with them (maxed sensitivty). This was originally boner city as ne one within 10meters would die in less then 2 seconds.
Heavies can no longer show off their dancing skills with strafing, BOOO!
Aside from that, heavies are still quite formidable. Ya we got a nerf but so did everything else practically.

I will say that forges guns are coming out more often than they used to.
75% of the time I would rock HMG and melt faces, now role has almost switched with the forge gun.
HMG can still poop in peoples mouths (within its new range) you just need to be more accurate.
See what happens when you hit someone on the dot of your reticle with a Burst machine gun (I was getting 1 shot burst last night, on ADV suits!). HMG can no longer be utilized as spray and pray, the DMG just isn't there.

NOW for newberts starting out in the game, they will ultimately get pwnd. Its almost not worth speccing heavy unless you have good amount of SP already. (~6mil sp). As a 1012eHP PROTObear, I am already having some trouble keeping up with top end assualt/logi players in advanced suits. There is no incentive for newbies to play heavy currently, without a CCP hotfix that will never come, the heavy population will plummet.

This game is a hard game to commit to with all its current trouble and bugs, but ultimately needs a bigger player base so that CCP wont be so desperate to empty our wallets and might be able to budget a bigger/better team for development.
NOOBS are super frustrating, but are necessary for our beloved game to thrive.

Nonetheless we are ultimately gambling that this game with be amazing 6months-1yr down the road.
So really, ENOUGH QQ MORE PEW PEW.
If you can no longer stand this game after a couple weeks into this Uprising build then find another game, the constant bitching and whining does not make our game better.

SIDENOTE: Ever since Uprising came out, my PS3 no longer suffer constant hard freezes (w/ PS3s IP set in DMZ in router).
I used to freezing everything ******* game and hadn't hit cap in the past two weeks. Lots of homos like me have this trouble stil, try this DMZ option if you have done the PS3's restore database and file system, unistall/restal dust clientl, game data deletion.....etc.
