You should change the title of the thread. If people associate anything with WoW they'll automatically reject it. As for my opinion: I don't think the game needs it. WoW needed it because armor mismatch was atrocious, and there were lots of unused lower-level gear that looked great. Destiny won't need this as long as Bungie keeps armor consistent. Maybe eventually it might be cool, just to give players even more customization and diversify their looks across the board.
