Whether they were drama-laden, sorrowful, humorous, epic, or whatever genre, I'm interested in reading about your gquits or gquits that you've witnessed. Maybe with some reasons and the events leading up to the departure. I'd also be interested in publishing a few of these on the blog, so fair warning here. If you don't want it published, make sure you mention it at the beginning.

My first ever real guild that lasted more than several months. It was a PvP guild. I was a Paladin. Yeah, the Paladin was my first Alliance character. All we did was preforms for like 10 months.
This was before cross-realm BGs. Sadly, the furthest I made was Knight Lieutenant (Rank 9 or 10 back in the day?) before I rolled a new Priest.
Nothing special about this one. Interest waned in PvP and eventually dropped leading to the creation of my Priest.

First serious raiding guild. They were on the cusp of killing Nefarion. Stoned by him 3 weeks in a row. I had just transferred in and magically, my first time in, we managed to kill him. I'm sure it was just a coincidence

. This was on the tail end of BC. We stopped raiding after that as BC was slated to release. Lots of players stopped playing after the expansion debuted. I was the first to reach 70 in the guild and was impatient as I wanted to enter Karazhan as quick as possible. At this point, I was dissatisfied with the leadership and the rest of the guild. This was the timeline where I wanted to progress faster and chase that same "high" I felt after killing Nef by hitting up Karazhan. I rose up the ranks fairly quickly and within weeks became an officer.
I voiced my displeasure at the rate we were going. After a few weeks with zero results, I moved on to a different guild and this one crumbled a short time later.

A fun and casual raiding guild. They just started Karazhan when I entered in and we plowed through it at a fairly brisk pace. Managed to kill Gruul too. I can't remember why I left. I know I wasn't happy about something. Different ideologies from the leadership I guess. They weren't taking it as seriously as I had liked. Again, I was left wanting even more. I was an officer at this point (again). And when you're in a leadership-type position, you have a level of expectation of others in similar positions (other officers). The GM had all but disappeared at this point and there was a lull in the hierarchy. No one knew what to do. No one wanted to assume the mantle. I knew a guild implosion was imminent. Ironically, it was my departure to free agency again that collapsed the guild.

Finally! A guild where I didn't have to be an officer or anything! I could just sit back and be a guy! Little did I know that wouldn't last very long. Many healers were in need of direction and assignments. The raid leader wasn't the greatest. I volunteered my services and assumed direction of healing. I had a great run with this guild during BC. Knocked out Mag, SSC, TK, BT, Hyjal, and Sunwell. It was loads of fun. I grew disillusioned at the way loot was being distributed at the tail end of BC. I was watching players who had hoarded a lot of DKP come in, get 2 or 3 pieces, and then not show up again. Loot was being wasted. I tried to make a point of this in the guild after being promoted to an officer (yet again).
I signaled that I would be moving on from this guild the moment Wrath released. I had the option to try to join in with another guild with ideals that I believed in or create one from scratch. Looking back at everything that happened, I decided to simply form a new one because at least if I was dissatisfied with something, I could make an impact move to try to resolve it.
I'm a victim of my own ambition. It's what led me here today. Sometimes it takes a few guilds to truly realize what it is that you want to do in this game. It took me about 3 years to reach that point. Lots of mistakes, lots of successes will come together and influence you as a player and as a person. It's like being enrolled in school for life as you're always learning and screwing up.
Sometimes being dissatisfied can lead to something good. Sometimes it won't. Thats my story. Hopefully some player will benefit from this wall of text. Whats your story?
