I think the price is fine for the Tank, the performance is still not attractive.
It performs fine for it's fuel cost, but manpower cost is still high for what you get.
The way I see it 1 T-34 is worth 2/3 of the other generalist mediums. But it's mapower is still around 8/10 of a normal medium. And between that and the teching costs. Getting them out in the numbers you need and maintaining a decent infantry force isn't really viable.
So relic has 2 options:
1. Lower manpower costs to better fit it's current exposable and spammable intent.
or
2. Buff it's performance and raise it's cost to be more similar to the other generalist mediums.
Any middle ground between these two will leave the T-34 in a state where it has no real advantage.
I also think ram can use a slight buff, but that isn't really going to solve the problem on it's own.
