As you said before, a single mine, pak, faust will ruin your day. And you will be trading T34s for nothing.
By the time it arrives, you need something that will let you recover all the mp invested. By this point on the game, all axis faction start to spike in their power levels either on vehicles or infantry upgrades. This is why you would rather have a T70 at 8mins rather than a T34 at 13.
yea, i have to agree with this.
t34/76's only strength is in numbers. but to keep the reasonable lead in the numbers game, as soon as you have 2 76s and enemy has 1 p4, you have to destroy it because 3 76s v. 2 p4s is not the same. even if you get to manage to keep 2:1 advantage, there will be more paks and tellers as the game progresses.
so massing t34/76s turns into "all in" game, where you have to constantly make plays to stay on top. and making plays with tanks is the most risky thing in the game.
