In Rainbow Six Siege - one of the most popular mmo-fps(questionable but you got me) - replayability is supported for 5 years by the seasonal addition of new operatives with UNIQUE devices. This practice saves the game from dying for 5 YEARS.
Why is this necessary:
To support online seasons the UNIQUE units and UNIQUE buildings.
To make existing units more playable. In fact, you can have 2 assault squads and a lmg-platoon. And you’re on top. Trust me. Why I dont need other squads at all? Tanks took my explosives, the team has my point of rebirth, enemies- got 73 rounds in the face in 6 seconds. At a long distance I can use my 2 stars carabine as well. Thats All, folks.
So, how to reduce the shortage of engineers and increase their favor in the game without breaking the balance?
In short, the essence - the engineer of the squad can ONLY build their own unique buildings + sandbags and hedgehogs.
Which unique structures will the enginer units in squads may have? Lets go!
Lmg squad - ammunition. The consumption of ammunition of machine gunners is the largest in theory, so they will be the most relevant in ammunition. After the stormtroopers, but it’s not a good idea to reinforce them more.
Rifleman - stationary machine gun. Let me explain, the task of shooters is rather defensive (as opposed to the ubiquitous stormtroopers), the machine gun will strengthen their defense capabilities and support the attack against buffed assaults.
AT-squad - AT-gun. Now there is no point in playing armor-breakers at all. I saw two tanks by my stormtrooper, got out of the trench and distributed a briquette of explosives, tanks down. To get tank with a PTRD i need a flank and aim the entire tank crew. So long. Adding a gun as a unique object to the armor-piercing platoon enginer will give them a greater advantage for the game.
Communicators. Who plays them? Well, seriously, what is the point of 4 radio operators, if the break between the art is still fixed. The solution is to give a respawn point ONLY to them. Next, a special opinion: Let’s make the point of rebirth WIRED. How is it? An operator with a coil over his shoulders pulls the wire from the common spawn point to the place he needs and installs a WIRED switchboard (telephone, spawn point). Communication during the war consisted almost entirely of wire points, to which it was infernally difficult to bring the wire. This is associated with a number of heroic acts, when the communicator clamped a wire in their teeth, shooting back.
The enemy is also interested - found the wire, went, looked, found spawn point. The engineer can cut the wire. Lots of mechanics and tactics!
This is a whole new mechanic and mini-game-the wire is stretched so that it is barely noticeable. At the same time, you can not be arrogant and put a point behind the enemy’s back. BUT the question is - what about radio communication, it was also during WWII!
BINGO! Premium squads of paratroopers and partisans will own a radio point can be build there you want it to be. The guerrillas will attack from unexpected places, as they should. Light weapons and a minimum of heavy weapons correspond to reality. On the German side, paratroopers will have hervorragende Waffe - special ops guns.

Snipers - their engineers will be able to build a closed sniper position or a fake person. I doubt it a little, but on the other hand, such a scarecrow in the window will cause fire and show the enemy’s position to the sniper.
NEW PREMIUM SQUAD: Paramedic - engineer can complete the infirmary. The infirmary treats fighters and allows you as filed medic to take one first-aid kit at a time.
The Soviet medical corps - girls. I know you guys argue with that but according to various estimates, the Red Army served from 600 thousand to 1 million representatives of the beautiful half of humanity, most of them was a paramdeic, including field ones. This can and should be reflected. In addition, anime fans will appreciate the variety of artworks on this theme.
German Sanitator! a strong person, healing genius with his sleeves rolled up and a stretcher slung over his shoulders.

Stormtroopers- I suggest that the engineers of stormtroopers give out a minimum, since the squad is now objectively more powerful than all the others by one and a half times.
Mortars. Let the engineer build a position with ammunition special for a mortar - 40-50 shots (not the thousands like now) + smoke shells.
Engineers-sappers. They have the most interesting thing - a disruptive wire charge. Put 40 kg of explosives, pulled the wire, sat down, wait. In the most likely direction of course. There is a horde comes. Get it! 10 frags. This charge can use the same technology as the wired spawn point and be no less useful, especially in defense. The practice of using such charges is in Company of heroes 2. And you can`t place it directly on the capture point.
Flamethrower. Their engineers can dig in the FOG-1 (and german analog) directional one time use flamethrower - a jet of fire is released in one direction for 20 meters. The difference from the charge is that the direction is a line, not a circle.
I will be grateful for criticism, suggestions and edits to the idea. The most important thing is to make the game live. The experience of Rainbow Six must be taken into game to maintain the interest of players. the proven technology will allow you to purchase units both separately or through the season pass.
And my best regards to the developers for their work and attention to feedback and suggestions. Darkflow - you are the best! So, keep calm and Hurrahh!
