When I was playing at 7pm GMT the feature of killing a player and taking ALL of their money was still in the game, for example.
Player 1 has $1576.
Player 2 kills him.
Player 2 receives $1576
Now however you ONLY receive $100 for killing a player regardless of how much money he or she has on their person, this has clearly been changed by Rockstar..
Where is the risk now?
