I just would like to see the old ones optimized. Also some units maybe tweaked than.
US Paratroopers? Recoiless Rifles like in CoH1
SdKfz 250 with more armor (resistent to small arms fire and maybe MG42 facing front)
normal Leutnant Gottlieb from CoH1
What i would like to see:
First of all - proper Matchmaking.
manuel reload from HMGs
fixing some Vet requirements
reworking some commanders
OKW:
221 back (or 223) and able to setup to work as caches.
Jäger Light Recon Vet 1 (Suppressing Volley with G43 as in CoH1)
OKW leFH 18 given proper vet 4 & 5 bonuses
le.IG direct fire, indirect fire range reduced to mortar level
Ostheer:
SdKfz250 armor improved
Assault Grenadiers (better RA)
Artillery Field Officer's Coordinated Barrage ability expanded to use available USF, OKW or British indirect-fire units
Brits:
Centaur nerfed (far to deadly) - compared to Ostwind or other 20mm
It is not all, especially Allies are missing but i am currently not home and that is what comes to my mind currently.
