That would fuck usf over in teamgames even more
This is mainly about 1v1. Teamgames wont get ruined. Teamgames offer a lot of combinations and currently pz4 is the most dominant tank, a nondoc counter will be a buff to USF
You could make the m10 the nondoc medium counter (High DPS lower pen) and the Jackson the nondoc heavier counter (Lower DPS high Pen).
...
If you just added the m10 than USF would have 0 nondoc options against Panthers Tigers etc.
That means an overbuff to the recently reworked USF and thats not my point nor fair.
M10 could still flank panthers btw and for the first time usf will use a neuron on tank fights...
