I love playing as EtoH, and they're not overpowered or underpowered. If anything, they're like the Protoss of Thrawn's Revenge. Their fighters and bombers are probably the best in the game, especially since their carriers spit out 6 (4 nsiss, 1 krsiss, and 1 scarsiss right?). On the flip side, the damn thing costs 4000 credits, which is quite a bit, more than twice as much as the Quasar Fire carriers, and more than MC80s, and just a little less than MC80Bs, and the EtoH doesn't have any cost reducing heroes. All of the EtoH ships are more expensive than their NR or IR counterparts, but they're also better in a lot of ways.
However, the economic advantage, or disadvantage, doesn't come into play when facing a similarly sized battle group. What I refer to is the population numbers for their ships. While Ascendency SDs (love them, btw) no longer have cloaking (I loved this, but THAT was definitely unbalanced), they're still much better than Vic Is and Vic IIs, and much better than Assault Frigates or MC40s, and yet they take 3 pop all the same. Not to mention they come with 3(or is it 4) fighter squadrons and one bomber squadron. The same thing applies to the EtoH's best ship (in my opinion): the Chaf frigates. These things deal crazy damage, love them, and yeah they also cost 4000 credits, but they take up TWO (2!) pop! I've contemplated making 20 of these and just jumping them around, blowing stuff up...No other ship can match the Chaf in terms of firepower with a pop of 2. Then there's the Phalanx Battlehammer. Beautiful looking ship, and it brings with it more fighters and bombers, and outclasses most other capital ships except for the SSDs, and is still just 4 pop.
So yeah with the cost discrepancy, maybe I can afford an NR or IR battle group twice as big with ships that are slightly inferior, but since only 40 pop can be on the field at once, this greatly closes the numbers gap. Basically when playing as EtoH, you're right in that they're at a disadvantage at the beginning but once you nail down the economy, (and a lot of their initial planets in the GC have high mine values) matching them in a space battle pound (or pop) for pound is damn hard.
In a land battle, they're not nearly as invincible, and damn their land units cost a lot. And I don't think they have any ground commanders, is that correct? Aurek Seven and Shial don't seem to convey any bonuses.
Also, I saw in another post that you guys are working on another defense option (in place of Golans) for EtoH. I actually thought that not giving them Golans was unfair at first but it makes sense. They also lack a planetary weapon for space combat, like the hypervelocity and ion cannons, but again it makes sense. They should be forced to field defense fleets to protect their borders. Anyway, my point is, perhaps they SHOULDN'T have any sort of fixed defense, they should be forced to keep a lot of their fleet at home.
And finally, I'd like to thank you guys once again for the incredible work you've put in. Not only have you done a great job putting together solid representations of the NR and IR, but you filled out an incredible and unique third faction with beautiful and awesome units.
