While I was on vacation, my guild shattered into two pieces. I was surfing WoW Progress and I noticed a whole bunch of "X has left the guild", which was a pretty terrible way to find out.
Like many raiding guilds, we've found recruiting to be very hard this tier/expansion. Through regular attrition, we gradually slipped to the point where we were getting 23-24 people on some raid nights. As we were working on hard modes, this made progression very difficulty. We'd get one or two nights where we could field a full raid, and one night where we couldn't
It was decided that we'd split into two 10-mans, so we could at least continue knocking down heroic modes. Unfortunately, the heroic lockouts make it hard to recombine into a 25-man, even if we had the numbers.
I gather that the other 10-man was having drama. It culminated in that entire group, minus our guildmaster who was in the group, leaving the guild. I felt really bad for our GM after finding out the scope of the split.
So we're basically down to one 10-man worth of people. It's a pretty solid 10-man, we go 6/7 Heroic Firelands.
Taking advantage of the new Guild Transfer Service, we've transferred to the Lightbringer server, a more populated server. I think the plan is to try and recruit back to 25s.
But I'm not really sure what the future holds.
