I believe T1 should only have soft AT, enough to make soft-skinned vehicles have second thoughts on charging in.
I do not mind the AT satchel if it's enough to just keep vehicles from charging in and/or there's the other idea of allowing the M3 to have enough penetration to at least chip armoured cars and half-tracks from a distance.
This means T1 players can have their cake and eat it too. They get mainline infantry with flamethrowers to totally deny garrison / cover use. Then they don't even need to tech up for 12 minutes because PTRS will handle anything the axis can field.
They get the benefits of a strong early game and little in the way of downsides.
Axis can't harrass 'cos the M3 can chase you all the way to base and wipe a squad.
Axis can't use cover because of flamers
Axis have to bunch up and lose map control
Axis hard counters are instantly countered by the same tier. Scout car vs PTRS = PTRS win. Luchs can't do much pushing either.
There should be a trade-off for the early power boost.
And why the hell do all Allied infantry have good handheld AT for their mainline and elite inf when Axis lights and mediums are weaker than allied lights and mediums and the OKW had their shrek taken.
