Engineer and Support Are Having An Identity Crisis

All classes are having an identity crisis because of open weapons.

This is true, however, support is the worst because it’s two counterintuitive classes rolled into one

yes. this! battlefield classes done wrong!! even tho its such a simple concept

1. The assault class should be reconfigured and called medic, carrying a first aid kit, defibrillator, and M320.
2. The engineer class should initially carry RPG, Repair Tool and mines (or perhaps the cover that is currently in support)
3. The support class should be the same as always, carrying an ammunition box, perhaps maintaining cover and C4.
4. The recon class, as the name suggests, must carry reconnaissance equipment and the beacon to infiltrate enemy lines.

I think this is more or less where classes should go and that they can all fulfill their function. 

Actually another forum talks about the roles of the classes for this exact issue. I like his approach 

Assault very aggressive give him RPG and SMG  for main weapon

Medic, support with heal bags and the assault for MW. Personally I would prefer the medic to carry the respawn beacon (work as a med tent)

Engineer, reinforce sites with LMG as it is MW and the ammo bag, let him keep the mines and better suppressing fire

Scout stays the same as the new coming changes should allow a more flexible type of play. Sit back & shoot or scout ahead and cause mayhem (assassinate, flank, flush, get creative with stealth)

Actually there a players asking for an increase on party size, your approach would tackle both problems and give them each a role to play 

I agree that this is the best solution to the constant class issue

And we haven't even talked about the Assault class. It almost has no identity at all. It has no team play role except for the Stim that makes capture points move quicker. But, play any other game mode and there's no team benefit. And since there's no tie down to use that class to use the assault rifle, why play as Assault? Just for the extra primary weapon? eh...

I hear that they're adding the spawn beacon to the Assault class and I don't like that idea. Keep it with the Recon class. That was one of the big benefits of playing as Recon. Plus, it balances the fact if Assault had it, you'd never be able to stop an enemy push b/c Assault class infantry would have so many spawn beacons around.

Give Assault the health, give Support the ammo. Boom. Easy fix. Then move on to other class issues and refining.

Engineer should also have drones to hunt recon (snipers)
