I suppose then that ignoring puppchens, pumas and stalling for panther will be punished by light armor.
All armies got their teching directly delayed, OKW teching was indirectly delayed now that you need light armor or hard AT yourself against light armor user.
Also, Su-76 can't really fight stealthed puppchens or flanking puma. Its armor is paper thin so even 222 will wreck it if you flank.
I think you forgot the scenario I was describing.
Guards are more than enough AT power to stop light vehicles like Luchs/Pumas. That alone makes Snipers almost impossible to beat.
A Puma won't help you at all because it's useless against inf.
You need AI vehicles vs Guards/Snipers but all AI vehicles are light vehicles apart from PIVs which will get countered by Su-76s.
Relic wanted to make light vehicle combat last longer. Too bad that Guards are powerful AI infantry that can also fight light vehicles with PTRS + button.
Guards should be AI squads. Button might be OK but PTRS are too much.
SU-76s will also be too strong with their current penetration values.
