Use your imaginations
New Retail Naxx is back cinematic
Chromie: “Someone said old Naxxramas was gone. That the scourge event could be repeated but never the same as the first all those years ago. That Bolvar was a real Lich King.”
“But what if they were wrong?”
“Plus they didn’t have a new contract with the transmogrifier and the ability to cross into other realms with a timejackclassiccrack swaglerigrifer!!!”
Chromie activates timejackclassiccrack swaglerigrifer…
Level 60 original Naxx portal opens up
Transmogrifier rubs his hands together. “Ahhh… here we go… business will boom”
Really, with WOW Lore and Blizzard game design… how could old Naxx logically never come back?
