Time to quit. That's the way MMOs go, until the next expansion. Or roll new characters and/or start PvP:ing.

Personally, I'm rarely hunting gear in MMOs. I find it so disappointing and short-living. Rather, I'm an altoholic and try all kinds of team combos. I also get all crafts and help out my family and friends. It seems to make the game seem fresh and last a lot longer for me. That's mainly why I'm boxing - I would get bored way too quickly with just the same single character all the time.

I always have some goal (which is never getting max-gear) that I'm aiming for next. Like getting the world-event breath-under-water necklace and planar focus for all my characters, or maxing out a new tradeskill by earning all the mats myself and not spending a single silver on the AH, or clearing all quests in a particular zone, some achievement, etc. Makes games last longer and I don't have to ask myself "What to do now?"
