A bit of back story:
I transferred servers to raid with a couple friends at the end of Cataclysm. We completed normal mode DS with some help from LFR loot, since we started so late. When it came to raiding in MoP our core group stopped showing for raids and we took some of the more social players in the guild, I say social because casual is NOT a good term for bad, neither is social but these guys/gals really only play to chat and do the occasional bg. Needless to say we aren't downing bosses, most of the social players dont really want to be there they just come because we ask.
Downing bosses isn't an issue and most of the time the core group is on daily they just seem to be less interested in raids. I guess recruiting is the most obvious solution but on low pop servers the pool of players is pretty limited.
So, to get to the point. Do you guys have tricks or advice for getting raiders to show up and/or on time?
