Yes, that's why I suggested minor buffs to t3 units. I also don't believe you'd be having problems dealing with US tanks if you hold both fuels. When discussing OH t3 people tend to overlook the Stug and forget just how good it is for the price, especially if you can get some vet on it. That's another reason I suggest a slight buff to the Ostwind, so the Stug can be used to its full potential in the AT role.
It's true that the game has been moving away from axis lategame dominance, but that's a good thing - the whole 'X faction must win in 15 minutes, Y faction must stall to late game' mechanic isn't satisfying and makes it impossible to balance both large and small matches. Of course if a faction is losing their advantage at one point of the game then we need to look at other stages (in this case the mid game) to make up for that.
How do stugs hold up against blobs? Oh yes instant death.
The issue is the same thing people were complaining about with okw. At any point in the game allies will have a far greater amount of better quality AT. Combined with the fact that their tanks are more cost efficient across the board.
Pre patch as okw, my squad composition was 3 volks with schrecks, 2 racketen and maybe a puma. Now, it's one SP and 2 racketens and a puma. I went from fielding 6 at sources of AT to 4. 3 of which have to be retreated if they are targeted because they are so soft and prone to dieing and wipes.
Same thing for the OH AT. I generally don't get my first AT unit until the 7 minute mark. I have to use rushed 222 and fausts to deal with light vehicles and scaling into late game every usf and ukf unit can field 2 decent hand held AT.
Both okw and OH have no real solution to deal with infantry using infantry because the allies get the best cqc units and the cqc units axis has are squishy as hell.
