Aren't a majority of these moggable already? My beloved Frostmourne, you tease and evade me still.
I still don't get why they can't just add a "replica frostmourne" and have it not be the lore weapon but a recreation.
Just give it to us as a transmog
Honestly, just make a quest line for Frostmourne for Paladins and Death Knights and make it like a 0.001% drop off the Lich King at the end of that quest line. This idea of not being able to mog it but your character can hold it in an event is kinda odd. They could just make it an ultra-rare like The Jackhammer from Uldaman so that way people can get it and it won't be common as the air we breathe. Those that want it can work hard for it and get it.
Wait are they low key confirming Frostmourne transmog?
