Yes. Should I not play multiplayer if there are no green games?
Again, multiple things affect the ability to loot. In an FFA system, people game the system and there are intrinsic factors beyond individual player control.
Please read Brevik’s quotes. They did not decide to use FFA loot over instanced loot. Instanced loot had not been invented yet.
Brevik has even said repeatedly that he would change FFA loot to instanced loot if he could go back in time. That is one of the 3 things he would change in D2 where the other two are auto gold pickup and removal of the stamina bar.
