I cant think of a single thing i want them to copy from d3.
But from d2 I want them to copy and improve:
- Runeword system (I simply love this system)
- Etheral items
- Drop chanses, make yellow, unique and set items actually rare. (a bit less rare than d2 would be perfect)
- Strong and unique followers, more to choose from, but as strong as the d2 ones. And make them work in groups like in d2.
