The armor values are small enough because as you say, it's only meant to chance slightly the dynamic on the current match ups.
I haven't tested the different match ups on the move (nor how much scatter would be a factor) but i do threw several light vehicles against the T70.
The change is a clear nerf on the T70, but not in the areas which i think are fine to remain strong (no opinion on vet 3 atm).
Don't focus in a single match up, cause i did consider the changes in regards to all other factions. Ex:
Flak HT: the buff it get is only focus on slight AT. It will still get screwed over by the AT focus vehicles (Stuart/Su76/AEC) and if caught not deployed and supported. T70/AAHT will still wreck it but i think those vehicles would take more damage and could probably die if they eat a rak shot and/or faust.
221/222:
The point to avoid the whole 444/666 spam is to cut down the AI once upgraded and that it can't deal with more armored vehicles such as the Stuart. The 221 been dirt cheap at it's old cost (200mp/10f) would still see use even with lower HP (we use it with 200HP back before).
We had 444/666 because the unit was ninja bugged at 15f while retaining AI and enough AT to deal with 320HP T70 and AEC, which was a heavier investment.
My view in the problem is the following one:
-T70 at 320HP with old AI was OP. So it was nerfed and HP was increased to 400HP.
-That broke the OH match up, specially after removing Mobile Defense clutch. I don't think you want a 30f 222 to deal with it.
-a 400HP 222 might make things better for OH in the SU match up while not been relevant at all against the USF (AAHT/Stuart). It might cause problems against the UKF match up, but you don't bring an AEC in the first place as an AI vehicle at all and without AI on the 222 while would you need to counter it. My only concern is probably how a 221 + 222 would work against the UKF match up.
