Diablo 1 skill system vs. Diablo 2 skill system Which should be used in Diablo 3? Or should they implement a whole another skill system? I loved the Diablo 1 approach: you could find or buy books and get spells. The skill tree is a good approach, too, but it tends to make characters "builds" instead of unique characters. Could this be improved? Could we learn something from Diablo 1? Which way do you want this to go?
