So i was thinking today as I was browsing the new artifact appearances. Most of these models are significantly flashier and unique than legendary weapons were, so why would we still be restricted on transmogging them? Most of the old legendary models are outdated and dont stand up to new designs, theyre fairly easy to aquire for the most part and many of the new models are homages to them anyway. What demon hunter wouldnt want the warglaives? I have shadowmourne on my DK that Id really like to get some use out of outside of TW dungeons.
We're going into an expansion all about doing content for your artifact, so why don't they give us the opportunity to go back to older content and work for another artifact appearance? We could even limit it to just the artifact being moggable to the legendary too.
