Nerf unit and in the same time buff they counter? NO
Yes exactly. Doesn't need to be a huge buff, just slight one.
Buffing Panthers, you will make all T34 and M4 useless.
In what game mode? A T34 is cheap as *** and can be spammed easily in a 1v1 and 2v2. A Panther is expensive as *** and can't be spammed by an Ostheer player in a 1v1 and 2v2, especially in a 1v1.
Last time I checked a sherman comes way earlier than a Panther, is a lot cheaper and you can easily have two to three by the time one panther shows up.
Ostheer Panther is underwhelming vs all targets, not just a comet..
