as you can watch this video, comet has 2.5 AOE but has less anti infantry performance then panther due to cannon scatter is 6.4. more important thing is comet has now vet bonus about reload speed. it has only accuracy 30% bonus at vet 2. I think developer intentionally limited its anti tank performance so it can focus anti infantry duty and support firefly's anti tank mission.
early design of comet was too op so it could do anti tank and anti infantry so well but continuing nerf mad it inappropriate with both of it.
my suggestion is this, comet 7.7mm gun scatter adjust 6.4 to 5.4~5.8 PZIV has 5.54, so it would be balanced when we consider its fuel price.and 20% reload bonus at vet 3.
