You've spent days upon days deep in the caves of the Gelkis slaughtering the men, women, and children of the centaur clan in the name of the Magram.
Your hands are near stained by their blood.
But today you have finally hit Exalted.
You return exhausted to Deathcaller Aisha and she hands you...
...a level 17 green axe from Redridge Mountains

I know it's a small thing, but the choice to give the Epic at the end of a long grind this model is such an incredible disappointment, especially for a custom addition.
As has been discussed multiple times on the discord, it would be great for this item to finally be given its own model which reflects its status and the difficulty that it took to get it.
My proposal would be to give it the appearance of the Mag'hari Battleaxe from TBC. This is a white vendor item from that expansion so it's not so iconic that it would take away from the Vanilla experience, however it is unique enough to work as an Epic within Classic. Plus its design would work incredibly well thematically as a Magram Centaur weapon.

Feel free to post any other suggestions below. Or if there's other items that have an incredibly ill-fitting model in the current game.
