I have been thinking about this very thing for quite some time. I thought of making a guild called [list=1] or something similar and doing the old world raids. It dos take a bit of effort though. First thing thats gonna be hard is keeping people entertained enough to learn those instances with fairly worthless gear coming from it. Not only that but getting dedicated crafters and gatherers to make the proper resist gear etc is kinda a pain.

I believe this would be a very useful thing for people though as they could learn how to use different strategies on the boss encounters etc, on top of the nostalgic memories of these places.

Of course I may not be able to attempt this before WoTF comes out, but I have already begun collecting lots of dark iron etc for the fire resist stuff, still not sure what all new patterns would be good for the fire/poison/cold resist gear. Since the older stuff obviously would have lower stats.

Anyways if anyone would be interested in a project like this you can get ahold of me on here or in game on Zzy, on the US server Aerie Peak Alliance.

PS. I personally have only had experience with Molten Core, Onyxia, first bit of Blackwing Lair, Zul'Gurub, and AQ20. Would like to see AQ40 the rest of BWL and of course Naxx.
