We'll there could be a couple of options for additional soviet at.
1. Find a way to balance the t70 or other new armor units into the game for the soviets. The goal of this would be too force the german meta to consistently add pak 40 or pg shreks to the german build orders. So now you ask how does this effect soviet at? It does in many ways.
1. A pak 40 can be decrewed and stolen. Make shreks drop a little more so they can be picked by the soviets. I don't think the soviets would cry so hard about the the uber pak if they could actually get their hands on one consistently. Although I think you would soon see some german cries to nerf it rather quickly.
2. Find a way to get the t70 back into the game early enough and increase the rear penetration it does to tanks. The t70 could work with the zis to take down mediums. If the t70 is a threat to the german rear armor you would see mediums turning to face the t70 and exposing their rears to the zis.
3. Implement commanders with some early call in armor. Balanced accordingly of course and then go to my first point..
4. Give guards an option to further upgrade their ptrs after tier 3 or 4 is built to something along the line of shreks.
....oh...oh... and don't forget: if all these won't work, please add in the soviet menu an "I win" button. That way, when they suck ballz on battlefield, they won't be forced anymore to use flood or other tiring tricks and cheats in order to win (happened to me almost every time when I was winning in last 10 games, but never while I was loosing).
Every single point is ridiculous:
1. Soviets are playing aggressively untill middle game and usualy gain more map and push germans around. If you tell me you can't do that.... well... L2P. A stronger T70 will bring us back close the point where we was after the release of Soviet Industry doctrine. Remember? T70 is fine as it is; the germans are allready forced to bring on the field a PAK40 asap. A T34 can hit the field before PIV. And if you tell me I'm wrong, then again, L2P, dude.
2. Same as above. If you're asking for a T70 like a PIV, keep dreaming dude. In addition, yeah, PZGrens are not worthless enough, now they should equip the enemy even more, right?
3. So in addition to M3, or your OP T70 wannabe, you need earlier tank call ins for soviet. Let's imagine a little a battlefield full of M3s, T70s and early call-ins. German player will camp in his base, no point in trying to engage.
4. This could be the only decent thing you said, but even this one is wrongly put. PTRS needs a slight increase in armor penetration. That it's the only think it needs.
How can someone say these things and pretend he wants balance?!
