I agree with your post, very nice. Especially I want to emphasize this part:
1. Panthers cost twice as much mp as a su85 and 15 more fuel. Not including the fuel cost of the t4 upgrade and building. Panthers are not a hard counter to su85s IMO, which out range them and whose guns can penetrate frontal armor fairly reliably.
MYTH: Long ranged direct fire units are balanced
REALITY:
1. Weapon range is the single most important vehicle stat in coh2, and often with range comes weapon power per shot. The ability to shoot across the map from beyond a monitor's width of screen resolution negates any downside to move speed. This problem is not limited to the su85 alone, but the elefant is also stupidly long ranged.
2. Soviets have many long range options that feed each other, specifically snipers for AI and su85 for AT, with an su76 for fun if you want quick IDF. 120mm outranges 81mm mortars, and the precision strike ability is button to get a free kill on whatever squad is trying to cap a point or use a support weapon.
The combination of Snipers and SU-85 is annoying and a game killer. If that´s decently microed, there´s nothing a German player can do about it.
Russian Mortars also have a lot of range and if an ISU-152 appears and parks behind AT-Guns and infantry and is used defensively, the only option is an Elefant. At-guns and SU-76 are the final blow and can give Russians further long range artillery options.
The range advantage of Russians is kinda ridiculous. I´m okay with Russians having more and better artillery options, that´s what their army was about. However considering tank combat, the range of the SU-85 is an annoyance.
A Russian tank outranging a German tank is bad design imo. Just because the SU-85 has a sticker on it which says: "tank destryoer" doesn´t mean it should get super range and accuracy. What about the advantage in optics the Germans had, longer barrels on their average tanks which gave a flatter trajectory and thus better accuracy on range etc. Actually it was the Germans which tried to keep the distance in tank engagements and the Russians rushing in, trying to engage on close range. They totally flipped the roles.
