No, the Comet can not easily 1v1 a Panther. The Panther wins most of the time (there´s a nice video of multiple Panthers fighting 1v1 with Comets, we had this discussion about the Comet multiple times).
Regarding the Cromwell and P4, both tanks have completely different roles. The Cromwell sucks in AI while the P4 does very well in that. The Cromwell is for swarming axis armor.
Each faction has different strengths and weaknesses. The Brits have the most cost efficient medium tank and very good AT options. However, they lack in the AI department and have problems acting offensively with their infantry.
The "high" price of OKW vehicles is justified by their superiour veterancy. You clearly fail to see the point of faction diversity and complain why unit x outperforms unit y in a vacuum.
Well, yes I'd consider myself as a "playercard bully". And why does your playercard matter? Because it's the easiest way to dismiss fanboys and people with L2P problems instead of proving them they are wrong in a long and exhausting discussion while they eventually won't step down from their biased view. It's a good filter.
I would take the comet over the panther every time.
What you seem to be discounting is the fact the panther have a considerably longer reload/cool down. The comet on the other hand he much better rear armour, speed and accuracy on the move. Once the panther is forced to move any advantage it had was gone. Missing a shot for a panther is not a good situation. As for the veterancy, comets get much faster and gets better turret rotation. Generally speed/mobility/consistency > amour/health.
I will admit to recieving a great deal of satisfaction playing axis, I enjoy the tanks. I think your the fan boy, because there is an obvious powerlevel/cost issue here and your standing with you feet dug in pretending like it's not an issue.
I don't think I said anything was secifically OP, I said that the cost of the units/emplacements was more efficient than any of their counterparts measured up against any faction.
1v1 for both okw and oh, I have over 50% W/L. Most of my games played recently are with my friend, who doesn't even own his own computer, on my 2 gaming rigs.
Two major points. Bring the cost in line with the performance of the rest of the factions. Nothing is op except for the Bofors in 2v2.
