I really don't understand this statement
T4 is too inaccessible for 1v1 use
Late-game OST armour is not particularly reliable vs infantry (unless somebody can afford T4). This makes Tiger-call-in doctrines one-way for OST
The majority of Tiger play is T1/T2 into Tiger. It has nothing to do with T4 inaccessible. Oshteer T4 is completely imbalance because it has no equivalence in USF and Soviet faction.
The issue isn't T4 but a lack of stock light tank and T3 being underwhelming (Pz4 and Ostwind). Late game OST T4 is particularly reliable vs Infantry or you have to tell me what is the Brummbar.
The Panther is a bit more an issue but only vs the Brit. The Ost panther is at his place vs USF and Sov.
Relic designed the assymetricality of Factions around USF/Sov being strong early game and weaker late game vs Ostheer.
You are currently acheiving a re-do of this for the good. So USF and Sov aren't anymore that much over Oshteer during the 10-15 first minutes. So my question is how do you plan to balance the late game if you make Ostheer T4 more accessible and more reliable that today to deal with infantry and medium tanks?
USF is still stuck into a unique T3 and Soviet T4 is actually no more powerful than Ostheer T3. If the Soviet player fail to seal the game on the 15 first minutes, he can't do shit with his stock units after that.
