I've said plenty of times that T70 are too cheap. Their cost should be increased.
But yes, two T70 should rape Pgrens, and one lone T70 well microed should rape PGrens too.
You shouldn't go NEVER with a single infantry unit against an AI tank.
People makes T70 specifically to counter PGs as they are an infantry hardcounter.
Why do you insist in that you want to kill T70s with infantry?
As someone pointed above, Ostheer have plenty of hard and soft counters, but you insist and insist in that you want to kill them with your shreck PGrens.
Damn, just retreat or garrison a house and wait for your T3 units support. Or ambush it with grens!! Even the most pro player can't see into the fog of war.
Is as if you wanted to see in T70 a unit that fills the same role of vCoH units like M8 or PE AC. But by design and tier placement T70 is more like a mini-Ostwind, with less armor and hit points, reflected in its lower price but with the same AI capabilities.
Nerfing T70 even more will make the unit useless when Soviet Industry got patched, because if they can't even kill infantry properly there's no reason to go T70 instead of T34.
2 problems with retreat, is that if it is a long way, T70 kills the fleeing unit and potentially forces shrek drop. Another is that if a single unit can reliably force away PG's then how can I expect to hold the field?
If grens do ambush they cannot kill the T70, they can only injure it for munitions and manpower bleed.
What if I am not near a house, what do I garrison? Do you want to restrict the German to remain near houses?
Ost forces inf to keep distance, which is what it is supposed to do. T70 has another role, not that of ost. Hit hard and hit fast, then get out of their fast.
In addition, what other early counters do Germans have to T70?
Mines- Too expensive must sacrifice other upgrades or fausts, not guaranteed kill
222- too little health now
Paks- miss frequently, although they often only get 1 shot off anyway
P4- comes out too late, what happens if German cannot get P4?
Stug- can actually be circle strafed by T70, German must give up AI capabilities, comes out latter
PG-large munition cost upgrade, what if I don't have it?, huge mp bleed, lower AI capabilities
I can think of no others. If you won't make PG's better against the T70, the pak must be more reliable. The pak in vCOH could always force away the armored car if it could fire at range. Right now the pak cannot reliable push back a t70, so I must rely on PG's.
PG's should stop T70's because that is what they are designed to do. Although PG's have strong AT capabilities they get riskier to use as game progresses as soviets unlock better AI tanks that can one shot squads. If they cannot be used early game to reliably counter light tanks and build up vet to deal with heavier tanks, there is a problem. If you are facing PG's with shreks you should have map control because he gave up AI capabilities and you should then invest in a T34.
T70 was not useless before soviet industry, it will not be after. You are not using it correctly if you think it was useless before soviet industry. Soviet industry allowed the exploitation of a broken unit in a more broken manner.
