Class gadgets and rebalance.

Practically all the classes can self-restore health and revive other teammates. At this point, assigning some of the gadgets should serve as a balancing measure.

ASSAULT

Rally Beacon instead of Spawn Beacon

Assault should not deploy a Spawn Beacon. Instead, a beefier version named Rally Beacon. By the Rally Beacon, Assault may also redeploy a stationary ammo and a med crate, so other teammates can also retreat and replenish themselves without stress. For balancing purposes, no explosives are to be gathered. For heavier stuff, the Support Class should be the only option, and his supply crate. Rally Beacon should be an Assault Class option available instead of the Adrenaline shot, which should go with the Recon class. 

Spawn Beacon could happily return to the Recon Class, because this class needs something useful. Maps are narrow anyway, and practically none of the players make use of the Spawn Beacon with the Assault Class. I thought it was a brilliant idea to grant the gadget to the Squad Commander. In fact, there is no purpose for it with the current gameplay mechanics and a lack of fully fleshed-out vehicular/aerial maps.

Smoke Grenade Launcher

Smoke grenades had been designed to obscure movement or to make a decisive push. Right now, medics possess the option to smoke a downed player's position and revive him. I think Assault should make more educated decisions about how to use the smoke grenade launcher. Medics should either use hand smoke grenades or nothing. Support class is already OP class in my humble opinion.

Med/Ammo small Pouches

Med/Ammo pouches for Assault. Assault has the passive quick-heal ability in one of the class passive traits, which is OP in my view. Instead, Assault could sacrifice a beloved Shotgun or Grenade Launcher slot for a Med/Ammo pack. I think players would embrace such a change, and Assault would be less spammy and overall more useful on the ground. Assault has passive heal and even quick heal in one of the class traits. Healing and replenishing ammo on demand are always a better choice. Sharing with others is always welcome. This would not make Assault stronger, but rather more useful, and deprive him of one spammy gadget. I feel like the flame grenade launcher needs a slight buff.

MEDIC/SUPPORT

Already a solid class.

Medic/Ammo small throwable pouches and the Med/Ammo crate.

Support Class has a Supply Bag/Crate with meds and ammo. Small Med/Ammo pouches are not interchangeable, making them a bit useless in the long run. I see that as a bit of a problem. Assault, on the other hand, used to have a lot of ammo on himself back in the day, and in the last BF iterations. Basically, med bags are currently stacking on top of one another, Med/Ammo bag. Pouches and Bags/Crates should be rather interchangeable, like in the old days.

Mortar

Mortar feels weak in the game. Instead, I would shift it to the Recon class because this class is always behind the lines. Mortar is kinda intuitive for someone behind the lines. Support should not be distracted by mortar in its current shape, in my modest opinion.

ENGINEER/ANTI-TANK

Perfectly balanced class. Classic approach, nothing has changed over the past 15 years! Well, the amount of ATs needs to be discussed. I would rather have 4 mines by default, up to 6 with a perk. I think mine should disappear 60 seconds after the player`s death. Not sure about that, this needs feedback.

RECON/SPEC-OPS

Probably the least favourable class according to stats and my taste also. To a Recon class shall go Adrenaline and Mortar. 

Adrenaline Shot

I believe Spec-Ops would make more use of Adrenaline Shot. Hearing footsteps better, moving faster, restoring health with it would be a much better option for the class with a Pistol for self-defence, and a Sniper Rifle as a long-range option. Such an item could be life-saving for a fragile class. Sniper could rotate faster with this and recover sooner. Sniper would have a better grip against other classes and could take them by surprise. An adrenaline Shot without a healing option is useless. Most players do not have good amplifiers with 5.1 headphones, so amplified footsteps do not count as much. Also, Recon could have 2 Shots and use them on a friendly player as a gadget option.

Stacking U-TGS beacon, UAV drone, scan grenades.

Another issue is stacking the same gadgets over several slots. I would rather have U-TGS, MAV drone, and grenade detectors as interchangeable equipment, unlike being forced to have all of them at once. Snipers should have anti-glare goggles by default, instead of U-TGS, to scan for enemies from safety. U-TGS, MAV, and Scan Grenades should rather count as a swappable gadget from the gadgets slot. 

Spawn Beacon

Spawn Beacon was an integral part of Sniper; a player received points with proper placement.

Instead of the quick heal passive ability for Assault, I would shift it to the Recon class. Recon is very fragile and needs a slight buff. I would remove 1 headshot, 1 perma kill ability, because this mechanic is a bit more of an annoyance and confusion for the downed player and medics.

What such changes would do.

All classes except for the Anti-Tank could fast self-heal on demand rather than regenerate health quickly. Optional or additional healing method for Assault and Recon class. Practically, this would even boost healing while making tactical decisions. Sniper would become more aware and mobile, more willing to rotate on the map with the Adrenaline. Assault could use more cover with Smoke Grenade Launcher, as it used to be in old BFs, and actually shape the Battlefield. Also, use less spammy gadgets, more pro-team ammo pouches, and a med pouch, making the class more similar to what it used to be.

PS: Sticky Grenades and Gas Grenades are, in general, cancer... please move Sticky Grenade to Recon Class, not Assault. I hope the gas grenade will be limited permanently to BR... not the main BF game.
