It should be DK only just as Ashbringer is paladin only, even though there was a Corrupted Ashbringer in OG Naxx.
When asked about the Corrupted Ashbringer being added to Secrets of Naxxramas, Ion said that for lore reasons they could never do that, and I agree.
There is absolutely no reason for a non Death Knight to have it.
Unless you want to remove all class restrictions for such weapons, then I’d be ok with having corrupted Ashbringer visuals as a Death Knight, and if it is that what you want, you could make a new thread to discuss “removing the class restrictions on weapons and sorts deleting class fantasy” I’d love to argue that with you.
You know I can make some artwork and probably put in a 3d model in the style Blizzard uses for the sword I don’t know if they’re willing to put that in the game though.
The other thing to note is that Frostmourne is actually a 1h sword, not a 2h.
My fave is the random NPC fishing at the DMF complaining about all theese random leggo and rare weapons instead of the 4 fish he needs to complete a quest.
Open it to all classes tho because Arthus prize weapon you guys already took and destroyed. Why cant my warrior have access to that lore? Because im not a DK.
Ashbringer was cleansed and handed to a pally as champion of the order hall - this is why they get a transmog for it and no one else - the same as dk’s get a 1h version of frostmourne.
So by agreeing that DK’s specifically get a destroy Frostmourne and create a new weapon completely negates the fact you want the transmog of the original weapon, and if it was created again it would bee DK only? Sounds like your issue with within your class order hall my guy.
To be honest the more I think about it the more fitting the twinblades of the prince fit. Frostmourne which is a symbol of the lich king the monster who twisted the dead into his most powerful warriors that were bound to his will. Now free they take his broken weapon and ressurect it and twist it into a weapon to suit their purpose.
