Ditto to what Taffy said. Myself, Greybeard, Jacks, and Ricky are all honored by our invites, but we're happy where we are.
And really....why try and break up the few English speaking guilds that are left? Personally, you won't ever see an invite from Pro Bowlers unless you are in a guild under 20 players. It's just common courtesy not to try and break up any of the very small circle of English speaking guilds.
However, if you want to shred up some Iranians and get some squiggly lines in your guild, go for that and leave the little guys as they are. Trust me, you guys have more than enough power in your guild.
