From what qwerty has told me, his o-alliances are not a leeching arrangement. This isn't quite how he's doing it, but, like, if me and Xin made a deal, where I'd get his jets one day, and he'd get mine the next, and on and on, wouldn't that be a mutually beneficial arrangement? And therefore not "leeching"? I still don't like the concept... it makes who your allies are a little too important because of how powerful offensive alliances are. I like top players just to avoid it.
