CBM games are not balanced as well. Although I really respect CBM and don't have anything against it, saying that CBM is balanced is just funny. Well, it is more balanced than vanilla maybe, also it opens many new strategies (and does this much better than actually balancing) but many nations are still crappy and many are still uber. And the removal of gem generators increased this difference even more for nations like Machaka, MA Oceania or MA Ulm. Well, this game is just unbalanced as it is and to really balance it you need to sacrifice thematic aspects which obviously neither the devs nor QM want to do.

What about Bane swords and fighting at arena, btw? What does CBM change about these?

Regarding the gorgon, my 2 cents. Yes, gorgon for 50 points is really cheap but does it become really easy to win with Pan when you have the, let's say, EXNXA2 Gorgon (one of the most powerful builds)? No, it doesn't. And if the gorgon in vanilla is so uber, why doesn't it let Pangaea win here, there and everywhere? Just because it doesn't. And when we say something is uber and should be nerfed, we should probably look at it in the context of the nation.
But, YES, the Gorgon does make Sauromatia ultimately powerful and, of course, 50-point gorgon even more so. But not Pangaea. And when you nerf Sauro by increasing the cost of the Gorgon, you make the life of Pangaea (which is not too sweet) in all 3 eras even harder. And this doesn't bring more balance in general.

And regarding Agartha, especially MA Agartha. How does CBM help them by increasing the cost of another "uber" thing, the Risen Oracle? Is the Risen Oracle immensely powerful? Yes! Does it make Agartha uber? No.
In my opinion, in CBM MA (and maybe EA) Agartha, Machaka and LA (and maybe the others) Pangaea, MA (and EA) C'tis, MA Ulm and the others are much, much worse than they are in vanilla.
