I sell off or destroy anything I KNOW isn't worth saving. If I'm not sure I buy more and bigger bags OR I move items to alts, some newly made just to hold such stuff. Of course on Firionia Vie that's much easier since even most quest items, old raid gear and other usually "no drop" items can be transferred.
This is half the reason I MOVED to FV server! I'm a packrat IRL and, of course, in game. I'm always worried that some quest item in the bank that I've long since forgotten about might come in handy some day when I finally decide to finish that quest and I can't stomach the idea of having destroyed something which could be useful ten years from now! ;)
Oh, I move stuff to my house too. My EQ house should look like those "rat's dens" you see on the news when someone is discovered dead in their home crushed when a 10-foot stack of old newspapers fell on them. Sure wish you could add extra rooms to your EQ house!
I'm waiting for the day when bags WITH STUFF IN THEM can be inserted into other bags!
