An accuracy buff isn't going to make it OP but minimalize rng. It is simply frustrating that the Panther misses shots while being deployed in its intended role.
Great so we will have a high armor high health long range blitzing high accurate tank hunter. Good luck have fun playing against that. Should we also give it non-doctrinal smoke while we are at it?
Currently the Panther is too niche to be fielded. The Panzer IV is a now brainer for OKW and Ost alike.
