The same conversation about Panthers, Comets, and the other zoo animals has been going in parallel in another thread.
Regarding Panther vs Comet, let's, first, acknowledge some hard facts:
[snip]
Now, what do you propose that the Panther sacrifice so that its RoF increases? Don't you agree that the charts show it is already very powerful as it is?
Now, I don't really have a strong opinion here, but you realize that 'winning' means there's a Panther that's one shot away from death. That's a razor thin margin to maintain across an entire tank battle.
It's not that the Panther beats the Comet, it's that the Panther is neutralized by the Comet. Not to mention the Comet also solidly shuts down Ostheer T3. Given that the ratio at max range is virtually 50/50 you have to realize that either side is at a major disadvantage for being on the offensive. And I'll tell you, the Panther is the first and only stock unit that Ostheer has that has the potential to assault entrenched Brits. (And by that I mean Bofors.)
Compare the Comet and Panther all you want, but I would wager Ostheer losing a Panther is far more crippling than a Brit losing a Comet. Comets come with, and are supported by, the British faction, which is what I think is really what grinds people's gears about the Comet.
That said, I don't think the issue is with the Comet or the Panther, but the kinds of units that may or may not be supporting them.
