IMO the biggest reason of the success of the 251 is that usually Soviets refuse to build T2 in response/anticipation of it and instead always want to stick to Penals and Guards PTRS softcounter just to rush the T-70. Which doesn't end well a lot of the time. It's exactly the same when Ostheer refuses to hardcounter (i.e. Puma) the T-70 and stall for medium armor instead. It's a risk and sometimes it doesn't pay off.
They refuse to build T2 in anticipation of the flame HT? That's your theory?
Please show me your playercard, I want to make it certain you have more than 10 games played as soviets...
The vet nerf changed absolutely nothing, this thing wrecks infantry in half a second, it will still vet in 2 minutes after getting an upgrade, besides already being an instawipe unit.
I find it mindblowing that there are still players complaining about the t70 in its current state, if you think the t70 is op or that it "wipes" retreating units, you need to have your own play checked...
