1. More Hellfire-like items to craft. As in a whole new class of items different from the regular legends or sets. Colored pink or something. lol
2. A special cow level-like area where only the best of the best of the best can survive. this level does not need any item to enter. It's open to all level 60 characters. The difficulty is like mp20 and can't be soloed in any way. drops are of the highest possible roll quality.
That's all I could think of now.
