Wil just have to wait and see unless you can provide replays from preview where soviet struggle.
They where strong and still are strong in late game.
The changes to Ram are nerf to ram/off map combo which needed a nerf, they meant as nerfs the T-34/76.
T-34/76 is a cost efficient unit even without ram.
I am sure why you are focusing in my opinion thou.
In live 1v1 they dont struggle. And are not op. They are solid. In 1v1 without ram the t34 is cost effective but nothing special unless massed.
I have no problem with the ele countering allied td's but soviets need a viable counter to it. And with these changes they wont imo.
In 4v4 t34's only viable use is to ram because its wrecked in an instant, it doenst last in nearly any engagement.
Its main gun only tickles panthers tigers and other 260 plus armoured units. Its ai isent strong enough to make it worthwhile, any at support wil force the t34 off before it does enough or any ai damage.
It doesnt have any utility to make up for it being the weakest medium.
Flanking is none excistant there, thats if the t34 had strenghts to flank to begin with..
without ram (wich is gutted with these changes) its is a pointless unit in 4v4.
I only focused on your remark because it stood out to me. Same with any that think nerfing an entire or near entire mid/late game of any faction for that matter is a good change.
