Let's not argue about semantics. If people talked about the LV phase the T70 was always included, and while you might make a difference between these units, the majority of the forum does not.
I am not arguing semantics. The argument was that it "arrives way later than all other light vehicles in the game" and I explained the reason. Units that immune to small arm fire (like light tanks Stuart/T-70)and can take AP rounds should arrive late and their timing should not be compared with unit that die to small arm fire.
T-70 with 70 frontal armor has x140% more armor than Luch and Stuart with 80 has x160% more armor.
I don't see the point why the T70 should be changed (I'd even argue it would be an overall nerf regarding SOV faction composition) and why OKW T2 should be delayed. Both does not make sense.
Because the unit is OP both creating problem to ostheer and making Soviet T3 option less disable.
Soviet are currently OP vs Ostheer and nerfing them would solve more problem than it would create.
OKW T2 comes at a perfectly fine timing. If people come to the conclusion that something has to be done about the T70, then be it. But at the moment I am not convinced that the issue is that huge.
Again T2 performance makes OKW T1 alternative far less attractive.
OKW are currently OP vs UKF and nerfing them would solve more problem than it would create.
Also in general power spikes are important to keep the battle flowing. Of course it should not be so severe that this unit wins the game for you, but if every factions techs to about the same power level at the same time there is no use in teching at all from a design point of view.
I did not argued that Power spike should be removed, they should thou be toned because they can easily lead to snowball effects as you also say.
To get back to the T70: T70 is fine against OKW, the respective OKW power level at the time the T70 comes out is fine for all three Allied factions. The only setup where I can see potential trouble is OST. So just give OST better tools to deal with a T70. Otherwise it would likely mean that all other factions need to be rebalanced. Of course this assumes that the T70 is atm fine for it's cost and timing (which I think it is)
And the both Ostheer and UKF are having trouble so instead of buffing these faction it is time to nerf OKW/Soviets/USF.
