I don't think it would've mattered that there would have been two versions of Naxx. As they are in different continents, and at the time of WotLK Naxx would've fit with the EPL lore as it was still leading from Vanilla.

Now I think of it, they could have had some great quests in the new EPL dealing with Naxxramas returning, without entering the actual raid. Possibly entering a phased version and doing some quests inside.

Yes, I would enjoy this raid being returned. I consider Naxx 40 the best raid of all time, back in the glory days when I raided it I never felt so good playing WoW. Nothing has ever beaten it's place in my heart, and it's likely that nothing ever will...

Bringing Naxx to Northrend lightened my heart until I actually ran it, disappointed as it's challenge was flattened, a shadow of what once was.

Yes, call it a QQ thread, I am butthurt. I'm simply lamenting the greatest raid of all time IMHO.
