Do you need different copies of Diablo 2 if you have different copies of LoD to play online? - diablo 2 bnclient.dll

3 of us want to play Diablo 2: Lod, but they do not prefer to buy all the different copies of D2 if we can help. It is half the price of the expansion alone buy. Any information would be great. Thank you!
