There are some pretty big guilds right now, but that doesn\'t mean people will envy them or anything. Players will only have a chance to truly develop their guilds and characters once cb is out. And since most of the older members are well stablished in their guilds, no reason for a major swapping. And let\'s face it, there is no in-game reason for that guild existence. What would be it\'s alignment? It\'s purpose? See what I mean?
If you really want to be in a guild that people envy, why not join one that has a in-game purpose and work hard? Better yet, roleplay =)
There is The Mercenary Guild, if you want to roleplay a mercenary. There is the Mirth if you want to roleplay a good aligned character. There are many others, you just have to see what will fit better in what you want.
