222 is enough against most light vehicles with exception of AA HT (which i think it has too high anti light potential) and enough assistant to tackle light AI tanks.
Regarding light tanks, both AEC and Stuart had been made pretty average to bad regarding AI, so you don't actually need AT to avoid been steamrolled by them. It's the same as panic reacting to a Puma (Yes, the Stuart from all those is slightly better AI wise but comparable way worst at AT).
T70 is the real game changer and guess what, from all light vehicles and light tanks, it's the one which is arriving the latest.
Would you be in favor of an armor buff or HP buff for the 222?
While the Stuart might not have as devastating AI as t-70 you can't just ignore it, and the 4 squads of RM running around. You'll waste all your munis on fausts or pshrecks, and your MG will be stuck in base or lost. Stuart and AEC can both roll in to your base and kill your medic bunker and low health squads if you just ignore them.
OST already has an anemic early game. I don't see why they should always have to invest 500 something manpower and some munis/fuel into some sort of (weak) AT option and cross their fingers that their opponent makes a big mistake.
Meta game wise, since like 2/3 patches ago, OH has been proved to be able to skip both T1 and T2 for a fast T3 Ostwind rush. 2 Pio + 2 MG + 2 PG or variations using AssGrens are common. The answer to this has been the usage of more light vehicles (M20 into Stuart/AA HT, T70) which provides a risk to the build. This result on people not skipping T2 if they are even or behind as they need the 222/Pak cause they would be too behind otherwise before the Ostwind has any impact.
PD: PG shreck is also risky to be your sole AT to depend on, but doable.
I don't think anyone serious is rushing Ostwinds. I'd say T2 rush is only a novelty stratagey. It works against conventional builds, but easily gets torn apart by someone who's seen it before.
Bad idea. Cause while it's a risk been without heavy/light AT on 1v1, that's not the case for teamgames at all.
I consider that while OH weakness to lights is a thing, post USF nerfs to M20 and adjustments through the years on power levels of lights, OH has enough tools to deal with them without requiring the hard counter that has been the Mobile Defense Puma meta.
Why exactly is it a bad idea for team games? OKW can field both luchs and puma in roughly the same time period, and just one of those at a much earlier time point.
I don't remember anyone complaining about the command p4 when it was a techless call-in. I don't remember anyone really using it either just after the Puma change, but I think both of those call-ins preformed an unspoken role as a possible punish to heavy LV play. Now that they're gone the meta has shifted to always using LV and light tanks against OST since they're such a strong investment with no downsides.
What are your thoughts about StuG in t2? With or without battlephase 2 requirements?
