You do realize once you're invited you stay at social rank unless youre multi gladiator?
Talb said on stream in whisper to some dude they are just using the guild to make gold and being 2.2 in a guild with better players does not make you as good as them. Think of it being a social in Paragon. You're in the guild yes, but you're not as good as them!
Also any guild with 2.2 req to join is a bad guild considering 90% of the people who gained it in mop/cata bought a boost. To confirm they didnt buy a boost, make sure 2k and 2.2k achi were not earned in the same day.
