Personally, D2 was my favorite video game at that time. Things change, technology evolves, tastes differ. There is no reason not to introduce a separate mode where there is personal loot (either selected at game creation or character creation based on what Blizzard decides). The original global loot mode remains. Old school D2 players get the game they want. Other players can choose to have a different experience.
“Loyalty to petrified opinion never yet broke a chain or freed a human soul.” – Mark Twain. While loyalty is usually a positive value, it can turn into a burden for people who like to stay loyal to subjective things such as opinions or convictions. Change is the law of life and our loyalty must always know how to navigate changes.
