No actually Panther has one of the worse accuracy even in base stats (only lower than M36 at range 0 that is not important):
M36 0.05/0.045/0.035
Panther 0.6/0.045/0.035
Su-85 0.055/0.045/0.04
FF 0.066/0.055/0.044
Worth noting is that M36 has x1.5 better accuracy over the other vehicles (0.75 over 0.5, FF might have 0.55) and that FF has a MID range of 45!!! only 5 less than Panther max range.
Finally M36 can also use HVAP that have even more accuracy.
So you want panther buffed to FF levels? May I remind you FF has the longest reload in the game at 8 seconds. Obviously it needs high accuracy otherwise the TD that has the slowest DPS in the game would be even worse.
The whole design of the unit is that of a 60range sniper, you can't compare it to the panther at all.
