i think they basically decided they could either make the drop rate a lot lower, or they could make it so you are more likely to get something, but you might have to fight a lot for something specific. Also they give each player thier own incontravertible roll, so you dont have to invent who deserves what item mechanics like in ffxi, and people who have to pass on items because they arent as highly ranked in their ls, or they came as a different job because people asked them to.

Given those options, i think this was a better choice.

but i was never a fan of the type of systems that had people setting up whole heirarchies on who should get what and who deserved what, which required databases and templates for everything, complete with rage quitting and running away to other servers with all your linshells loots.
