well you are certainly the best MRA out there, i wouldn't argue that. and it is true, not all MRAs fail. if you can actually get all of your members to be really active and do what they need to once you go to war, with your numbers, you should be unstoppable. the only problem with that is that isn't what happens 99.99% of the time. the good players get leached off of trying to protect the simmers, and they eventually fall as well because they no longer have the troops to protect themselves. not saying it will happen to you guys, just going by how things historically play out. maybe you'll prove everyone wrong.
either way, best of luck to you. we aren't neighbors, and we each only have a couple of cities in the other alliance's territory, so i don't see your alliance's success affecting us very much at all... at least for now
