Engineer diversity
Soviet Engineer, Allied Engineer, Epsilon Engineer... Kinda boring. Lets add some diversity?
Replacement for the Soviet Engineer: Mechanic.
Let me start off by saying that; the Soviets are lacking when it comes to field repair support, due to their inability to produce dedicated repair units via war factory.
You could argue, however, that their repair drones superior abilities (being amphibious, and instantly called in) compensates for this, but they're still quite easily picked off, while the other sides can easily mass produce theirs onto the field, giving them the edge over the Soviets in field repair support, hence how the Soviets are lacking in said division.
I find this unfortunate, too, due to the Soviet side being the side which emphasizes unit superiority.
So that's a problem I find with the game. Now it's time I suggest a solution to it, to even out the great balance.
I propose to you; the Mechanic. What is the Mechanic? The Mechanic is the replacement for the Soviet Engineer, which, is; in all sense still a Engineer (Still able to capture buildings, extra...), but with the added ability of slowly repairing tanks at close range. Think of them as Field Medics, but for tanks. Having a Borillo filled with these guys would most definitely come in handy for field repair support, and is a lot more producible than the repair drone... Because the repair drone isn't producible 
Replacement for the Allied Engineer: Operator GI.
I propose to you; the Operator GI. What is the Operator GI? The Operator GI is the replacement for the Allied Engineer, which, is; in all sense still a Engineer (Still able to capture buildings, extra...), but with three Addison's:
Addition 1: A weapon. To make up the for the Soviet Mechanics ability to repair tanks, the Operator GI is now equipped with a handy, short-ranged shotgun. This however; only provides little defence for the Operator GI, making him a very inefficient means of combat.
Addition 2: Added armour. The Operator GI wears a sturdy vest that supplies a bit more armour to deal with small arms fire, making him the strongest of the Engineer class infantry, however; The Operator GIs speed is slightly reduced due to the bulk of said gear, so it's sort of a triad-off, so to say.
Addition 3: Tent Deploy. Seeing that every GI class infantry has a deploy function, I figured that I'd give one to the Operator GI as well. On the battle field, the Operator GI can deploy into a small army tent, which can garrison up to 4 infantry. This however; only supplies a little extra armour, and can be easily overwhelmed.
As you see; as opposed to the Mechanic being unit support, the Operator GI is more infantry support.
Replacement for the Epsilon Engineer: Hacker.
I propose to you; the Hacker. What is the Hacker? Well, seeing that Epsilon is all about taking control of their enemies and using them to fight amongst themselves, hackers are nasty little infantry you should keep away from your base at all cost, for; they can turn bases against themselves. What makes the hacker so devastating is that when deployed, they can hack into any structure, be it building or defence. However; hacking takes a long time, which leaves them very open for a long time. Think about how long it takes to erase a building with a Chono Legionnaire, the duration it takes is as identical of a duration as it is to hack. The process however, can be speed up with multiple hackers hacking the same thing.
Due to their expensive gear, they're the most expensive Engineer class infantry, being $450, making them not as efficient at straight up capturing tech-buildings, but if you can utilize their hacking ability, it's well worth it. They also take a bit more health away from buildings so it takes two (at a net value of $900) to instantly capture an enemy base-structure instead of the usual three (at a net value of $900).
Hackers (only when deployed) essentially mind control bases, so they're pretty befitting to Epsilons theme.
I know this is a lot to ask. It's just something I want to share.
