First off, he only has a mainhand because you can choose to dual wield these weapons or use a shield if you are fury/prot, and soooo many shields match this set we didn’t feel the need to stifle creativity. If you are an arms or titans grip warrior (or perhaps a Ret Pally/DK) then Armageddon is a perfect choice. The design is more or less just a true warrior armor set, nothing special other than it looks badass. The bandages are difficult to see from the front on some races but almost always visible from behind, which is what you’ll end up staring at the most anyway.
A lot of this set is crafted, with a few dungeon drops and quest rewards. As such its very easy to farm up, although if you go for Armageddon you’ll have to raid Naxxramas, and could very possibly have a lot of competition for the sword as it is a fan favorite for sure.
