You can still split farm all you want. There\'s no rubber band attaching players to each other, and you can all go where you like, D2 style.
The exploit thus far in RoS was that all the bounty rewards were shared throughout the game, which was 1) cheesy, and 2) encouraged players to split up and run every different direction which made for a lame MP experience, and 3) very different from D2, where there were no shared bounty type rewards to exploit. In D2 there was no difficulty setting until the /playersX command. Prior to that D2 was all about multiple parties in the same game to create a higher difficulty/exp/drop rate. But that\'s not necessary in D3 since the difficulty setting creates those factors.
