My post demonstrates how the lower target size does not bring the desired result.
And my point is that instead of (only) lowering the size of mediums that affect all weapons one should be lowing the accuracy of TDs...
Can't look it up at the moment, I assume the Panther has the same base accuracy (different curve obviously due to 50 range)
One thing that should mot be forgotten though is that accuracy is halved during movement, and at least Panther, Jackson and Firefly are supposed to shoot during the movement, too.
Also, the balance team aimed at making mediums a bit stronger, not only at making TDs less efficient.
For purely standing TDs I avree though, the difference would not be big
