I'm still going strong, but it's because I found an interesting niche with a dedicated fanbase.
About half of my experience is a regular raiding experience with a "casual serious" guild. The guild supports two 10M teams, and while I don't have a permanent spot on either, I'm a regular sub. I could push for a permanent role, but I honestly enjoy the freedom of not feeling obligated to raid, but still staying geared and skilled enough to do it.
The other half is the all-hunter army that a buddy of mine founded. He remains in charge of probably the most popular hunter-exclusive site on the web (and also blogs for WoW Insider), and I've become his #2 in command for filling in with blogs on the website and leading various things in the guild. Last expansion we killed...I think it was 7 current-expansion bosses with all-hunter 10 or 25M groups, including one in Dragon Soul, the final raid of the expansion. Incredibly fun, unique, and impressive to a large portion of the community. Leading those raids was a trip, because you're determining brand new strategies (without traditional tanks and heals) without the benefit of tutorials or data. The in-game guild has hundreds of hunters though, and there's all sorts of fun on a regular basis, including large-scale world events like those in the videos above.
If it weren't for that group, I'd have been done a while ago. Pandaria is, by all counts, pretty cool, but my play experience is directly tied to the hunter community. Any cosmetic changes are superfluous to my reasons for playing.
Here's our most recent event:
YouTube video
The guy in charge was lag-spiking, so this was put together entirely by me, which is rare for these events (usually I just contribute occasional footage). Head to youtube for full-screen, for some reason it has large black areas on top and bottom when embedded (still working on the ideal ratio for youtube on my video settings).
