Personally, I believe they should keep the shared loot from original D2 in D2: R. If they were to do personal loot, though, it should follow the same “total” amount of drops that would have dropped if it was a regular shared loot game.
Example:
8 player game with the regular shared loot from D2.
Party goes through, and kills all end Act bosses(Andariel, Duriel, Mephisto, Diablo, Baal).
Let’s say there is a total of 10 uniques that drop between all of these bosses in this 8 person shared loot game.
Now, let’s say that the same game was instead on personal loot instead of shared loot.
8 player game with personal loot.
Party goes through, and kills all end Act bosses(Andariel, Duriel, Mephisto, Diablo, Baal).
Even though each person has their own personal loot the same amount of 10 uniques would drop, but depends on who gets it. This way would help against leechers, and pickit botters. Items would still be allowed to trade to other players.
Conclusion is that I prefer original D2 shared loot. But, if they do go to personal loot, or even as some suggested to have it as an option between shared loot, or personal loot as long as the same amount of “total” drops would be calculated then it would be fine to have it that way.
