If you raid for loot, you're done with the game when you have all the loot. Maybe the bosses should drop NOTHING at all, so then playeres would play for the content, experience and human interaction.

In 2003, I recall raiding bosses that literally dropped nothing useful at all. In fact in older mmos gear was much less significant. IMO only since WoW has gear been eleveated to the end all be all.
