This is pretty infuriating after all the assurances that we could join "whatever grand company we liked best". So I guess everyone gets to spend the next few days trying to convince all their friends to join the grand company they want to join. It'd be nice if we got a quick clarification that the bonus wasn't anything major, but it's already Saturday in Japan so we can't even hope to get a reply on this until Monday, the day before the patch.
