My guild is a very friendly, casual guild with a longer history and has had great success in previous tiers of raiding. We got hit hard by the end of expansion blues. Several of our more active players and officers took extended breaks, a few players quit wow, others had some real life issues take them out of raiding for a span. Several months ago, raiding almost completely stopped. We went from a 25 man guild progressing dutifully through ICC to not having the online members to fill a 10m ICC. At this point, we had downed 8/12 bosses in Icecrown in 25m and I believe our 10m group was 11/12. We were often tied or close for 3rd horde progression on our server. Admittedly, not a power-house server, but we were making progress. Even as we were doing fine, set to continue, the series of personal burn-outs and real life priorities reduced us to 1 of 6 active officers.
