Don't try to confuse the topic because you have no other retort.
You claimed that the panther changes were "logically a buff" (based on pointlessly comparing it to the Churchill)
If you look at the numbers, the changes seem to agugably provide a decrease in performance which is "logically" a nerf.
Let me explain to you in 1 line why panther was buffed against TDs, but is still not supposed to be their counter:
TDs have massive penetration, they already are reliable and penetrate most shots against panther, increase of HP takes away uncertain RNG element and gives you 100% probability to last for one penetrating shot longer, which gives you additional few seconds to evaluate your position and respond accordingly, but you are NOT supposed to counter these TDs without a flank on them as they still are designed to chip off your HP from greater range.
Mediums will have just as hard time against it.
Premium meds and Heavies which have more reliable guns will always require 1 additional reload to take panther down, elliminating the need for lucky RNG for panther in close situation.
TDs already penned armor easily and will continue to do so, but require one more shot now instead of lucky RNG, giving you certain time to react, which you otherwise would not have.
Logically, its a buff to survivability against TDs by eliminating uncertainty of RNG armor while providing reliability of HP and no amount of REEEEE is going to change it.
