from my perspective it was ok to voice opinion over the referral program - and it was discussed several times in executive meetings and it was felt that the reward was worthy of the challenging task. We realize it isn't a cake-walk to recruit 5 friends, which is why the reward was asked to be cool.
And as I've stated elsewhere - the program is really intended for players who are enjoying the game and having fun and want to share their love of the game with their friends. If that isn't you, then the program really isn't designed for you. I don't think it does anyone any good (including the community) to bring people into the game who really don't want to play it in the first place - or to purchase their own subs just to get a reward - it doesn't help the game to do that. What helps the game is finding more people who do enjoy and want to play the game. I know its hard to gather from reading these boards sometimes, but there are quite a few people who do enjoy and love this game.
Is the Galaxy X only going to be available via referral? Probably because that is what it was designed for - but who knows... things can always change.
