I know that Tirion has the Ashbringer right now and he's the weilder of it and so on. And while I think the only way this VERY unlikely boss of icecrown could happen was from a long phassing quest chain; I'd like to see the Ashbringer as a Weapon brought back. I'd like to see some quest dealing with the Scarlet Crusade/Onslaught because of it. Even if the only way to get it would be going back in time for some reason (say Caverns of Time issues?) or something.
I'm sorry I'm so vauge on this, I haven't had a chance to provide good examples, I just find it lame that such a Weapon is gone, one that had quest and ushc on it, and had so much story to it. Weapons lilke that seem to be gone these days, the new Legendary weapon might kind of bring it back it doesn't seem like it will be as fun or as cool using it. It doens't even seem to be special like Ashbringer was. If oyu ahd Ahshbringer, anyone who saw you KNEW you had Ashbringe. If someoen sees thise mace, because it has no glow or anything that really makes it show up, I don't think everyone would know you have it.
