In a personal loot system, the maximum loot a leecher/cheat player can get in 8 player game is 1/8 of the total loot.
In a global drop system, tbe same leecher can get 50% or even more of the loot.
The global loot system is FAR more exploitable than the personal loot system.
I prefer personal loot because I dislike cheaters and want integrity to be rewarded.
