No offense but I can post as often as I like. You sound to me like someone that has come to coh2 without ever playing coh. See I played coh from the first month that the game came out 8 years ago and I have enough experience in coh2 to know what up.
Ok where to start.. at nades cost fuel.. yep they do but they are a no brainer upgrade that has 0 influence on tech or the soviet choices in general. Its not a option of getting them or mollies or getting them instead of something else, as a soviet player you just get them they might as well be free.
Chek out coh for a road bonus, the vehicles are basically 2 times the speed that they are on the rough ground, this means you can use roads to actually make maneuvers, in coh there's hardly a difference.
Does the panther have more health and damage? Yep but is it substantial in game? health wise sure but damage no. When a unit that is designed to kill tanks, costs 2-3 times more then the su85 actually struggle to kill a su85 while flanking and what I mean by that is it takes more than 3 shots to the rear then you know the game is flawed. Go play coh just for a few matches watch how fast a panther goes down to at guns from the front, or how quick a m10 can mess up a stug from the rear... now go to coh 2 and watch the panther make a meal out of the su85 for like 30 seconds meanwhile it can be shot buy a swarm of at guns or get engine damage from teir 0 troops that cover the map.
Post as much as you like, just two separate THREADS on the same thing/s in as many days seems to only be clogging up the forums and make the discussion of it harder to follow. I played VCoH for the last six months or so before the move to the Steam servers. It's the first online game I really got into (albeit at a low level) and I think it was/is a better game by the end than COH 2 currently is. I think there have been a couple of steps back, a couple forwards and a couple sideways in the changes between the two games.
AT nades are usually bought by the Soviets because they are borderline essential against Scout cars or FHTs. They do significantly delay the first T-70 or T-34 so if you can skip them (say, you're up against pure grenspam to P-IVs) and then buy them later in the game, it's not a bad idea to do so. Tell me, if Panzerfausts cost fuel would you say that of the Ostheer?
Roads make a pretty obvious difference for me playing with light vehicles. I can't tell if and how much that has actually changed from VCoH. In particular, this is why the Moscow Outskirts map is so good for light vehicles.
A panther has just slightly less than a
95% chance of penetrating an SU-85
frontally, FYI, which is where the AT difference really comes in. It doesn't conceivably cost three times as much, however you work out the teching costs...
I think even a P-IV has a 100% chance of penetrating an SU-85 from the rear. I believe it should take four shots for a Panther to kill or disable an SU-85. Obviously the penetration is even more of an advantage for it against more heavily armoured tanks, like the KV-8, KV-1 and IS-2. Again, while I agree with some of your points, many of them are directly contradicted by the stats and the game itself.
