Well and we have our own problem with panthers. Panther is RNG BS tanks, sometimes it misses 5 shots in a row, sometimes it survives frontal engagment with 2 t34-85s in point blank range with less than 1/3 health at the begining
I always ram panthers to finish them with 34-85s when unsure about result, it safest bet to get rid of it, besides ram helps to catch up with blitzing panther.
Obviously, any infantry-based AT is good deterrent factor against panther, but its not gonna kill it untill panther decides to stand in front of 3 at guns (and they will bounce half of their shots anyway), but in tanks engagements it as close to being unflankable as it gets.
To sum it up, panther is not ultimative tank, but it kinda imbalanced from lack of side armor, and cause huge amount of frustration from miracle RNG sometimes. But then again i hate how inaccurate panther on the move (but, to be fair, command panthers mark target neglects that weakness).
