Why did you adjust the Ship Ratios? You've always been saying that they would be Equal, and a All FR/De based planet usually has 10-20% more value in their class than other fi/co/cr/bs attack classes.

So yeah it they have trouble hitting Etd, but the point is if you have a properly running BG, and 6 man All xan group and sucessfully attack into any race set up, any gal set up and be able to land most of the time. Now you take a 50 man all xan alliance going Xan Fr, where they can send 80-100 attack fleets a night and be able to roid ANYONE they want, and still be able to defend with 80+ Fleets is a bit insane.
