Alex, I have no idea why you keep trying to bring OKW into this. OKW can handle it just fine, it's Ost who can't.
Because in 2v2 you can have 1 Ostheer and 1 OKW. It has to be taken into account that the Soviet T3 change affects other factions different. And OKW if you go for a mech start won't be able to handle it due to the Puma being countered by a T2 start. I just don't like the fact this almost forces a T1 start.
This thread is for the discussion for the patch change in general.
EDIT: This is also map dependent, on open maps the T-70 and Quad Mount's ability to kite while be quite brutal. While on urban maps were the rackten can garrison the impact will be significantly reduced.
