Comet doesnt kick any ass, its ass itself. Its worse vs tanks and infantry than panther while costing the same.
Last round of nerfs was to make it not batshit OP because back then it was better than panther in everything (guys behind balance going from extreme to extreme here).
Its not a t34/85, its a panther. I dont know how blinded you have to be to not see that. Same cost and being placed behind 50 fuel upgrade (similar to ostheer) is very clear sign.
White phosphorus, crew grenade, hammer tracking, no vet blitz and normal smoke are all contributing factors to the units cost, not just it's combat performance. So yes, the panther does its jobs better for the same cost, but the comet can do more. The panther is SUPPOSED to be better than the comet, as seen by the nerfs the comet received so it wouldn't beat the panther 1/2 of the times. The comet beats p4s and stugs and anything below the panther handily, and for everything above there is the firefly. The comet isn't supposed to replace all your other armour, the old comet could. That's bad design. Does it need some love? Yea. But should it be single handedly smash all of Germany? No.
