I'd say it's just a lot of poor timing.
I mean ... there's only one month left and very few low level players at all...
Or at least, the next 4 weeks are level 50 oriented.
plus, there seems to be a misconception that stats don't matter, at least to some.
I partied a couple weeks back with a fellow Pug, and i was hitting melee for 50dmg with my double melds,
he with his basic cheap end whatever gear was hitting for 7.
So if you're trying to do stuff in the 20's and 30's, it's an uphill battle this month by default.
Also, there's no way in the current version to boot inactive players from your linkshell,
so people have adapted to be cautious about inviting ... at least enough of them to limit Ul'dah shouts for open invites. but if you google it with your server name, you can find plenty and apply on the main website and usually they are very welcoming. In general, i have found this community to be much more welcoming than any other MMO i have ever played.
