T1: Grens - fix rifle nadeWhat fix? Like halving the range once suppressed?
T4: Panther - increase AI capability of Panther to MATCH that of P4.You unknowingly opened the gates of hell by even suggesting that. The 4v4 demons will eat your soul.
T0: Cons - change weapon profile to beat grens at mid/short range, lose at long range.That's already the case, you should have played the game long enough to know that. It's more a problem with getting in optimal range without casualties and 4-men squads sticking better to cover.
Your other suggestions basically lead to anti-everything-penal-in-M3 spam that can only be dealt with by a Pak40 or Tanks.
The uneven relationship between tank call-ins and especially soviet T3 was not addressed at all?
