Suggestions for infantry classes design: Are these designs worth trying?

I imagine that making class system overtly complex monster leads to dumping down team play. Why? Because you're able to do so much by yourself that you don't need teamwork, coordination, squad unity, tactics.. . whatever to accomplish a victory. One man army syndrome — era of omnipotent soldiers.

Down here is my proposal, I wrote some time ago. Simple roles, more role-taking.

I personally believe that too much duties (gadgets and other gear/class) is making playing a class too complex. This complexity creates a fantasy of one man army phenomenon. I would go to opposite direction; sharing responsibilities and simplifying class roles to their absolute core tasks. Here's my proposal for Battlefield title in future developement. I made a thread about this sometime ago.

Assault - Primary role is to engage in combat with enemies at medium range. Could be able to destroy fortifications. Equipped with assault rifles, underbarrel launchers/underbarrel shotguns and bodyarmor supply bag. 

Medic - Primary role is to revive and heal teammates. Could be able to build fortifications. Equipped with carbines, defibrillators and medical bags.

Anti-Tank - Primary role is to undertake anti-vehicle warfare. Could be able to destroy fortifications. Equipped with submachine guns, anti-vehicle launcher and combat ladders/zipline.

Engineer - Primary role is to repair or destroy vehicles. Could be able to build & destroy fortfications. Equipped with shotguns, repair wrench and anti-vehicle mines.

Support - Primary role is to provide suppressive fire against enemies and resupply teammates. Could be able to build & destroy fortifications. Equipped with machine guns, ammunition box and field mortar.

Special Forces - Primary role is carry out stealth and sabotage missions. Could be able to destroy fortifications. Equipped with sound suppressed carbines, C4 and SOFLAM-PLD.

Sniper - Primary role is to engage targets at long distances. Could be able to build fortifications. Equipped with DMRs and SRs, Spy drone and Claymore.

Squad leader - Primary role is to lead a squad and guide players. Equipped with carbines, binoculars and spawn beacon.

Commander - Primary role is to lead a team and manage Commander resources. Equipped with SMGs, turret emplacements for base defenses and repair wrench.

lol, just for fun, it's only a few days away from release and they can't possibly change anything

The current four soldier classes are well but could be more fun. Each class is assigned one or two roles, such as the support class handling supply and rescue, which is a solid approach. However, there should be more ways to carry out these roles. For example, the support class could clearing the battlefield to overcome the fire and help teammates reach those needing rescue. The ultimate goal remains rescuing teammates, but the process can differ. Additionally, each class should have fixed iconic equipment and skills to clearly define their core roles, ensuring they done the job regardless of accessory changes.

Class exploitation. Assault and support can easily replace recon and class balanceis broken overall. He went for a complete overhaul while I tried to keep the same format they currently have.

I know its very unlikely that they will change it but I enjoy the discussion on how it could have been balanced better. As their current format is basically 2042 but no special characters. 

What problem does this solve? Why would they need to change the entire class layout at this point?

Cool, still think that robot would fit engineer or recon better. If given to recon, they could add a feature to give simple commands to direct the robot to aid allies since recon would have a better sense of the field and provide fire support. 

Mortars are tough to place but since recon is the one that marks enemies, i think it would be easier if another class carried and fired the mortar. I do see your point but that depends on the driver, can't  tell you how many drivers would rush in as their vehicles were about to blow and I was trying to keep them alive telling them to fall back. Can't save those who don't want to be saved

Your idea is cool! a danger-sensing passive for the Assault fits their role well. My original plan for the passive was also to counter flanking, and your design adds to the battlefield vibe.

For the Support’s Sentinel robot dog, I see it as like a unique team buff to protect the team. In games, few pick mines or active defenses, though they’re common in real combat. Since placing mines or defenses isn’t fun, the automated Sentinel robot dog handles it, matching the Support’s role of aiding teammates from the back.

RECON
i agree Mortars aren’t typical for RECONs, but it’s for game balance. Every class needs a heavy weapon, and RECONs have the most time to use mortars. They less fight upfront or repairs/rescues, so it suits them to stay back and use mortars. 
if giving mortars to Engineers would make them too versatile, juggling anti-personnel, anti-vehicle, and repair tasks.which spend a lot of time. If the tank has an emergency at this time, it may be too late to repair it. I want Engineers focused on anti-vehicle and repairs. Plus, carrying two heavy weapons would be too much for them.😄
