Hotfix for Greater Rift Exploit
A bug is fixed that was used to make multiplayer Greater Rifts easier

The bug involved players leaving a game with a Greater Rift, at which point the health of the monsters would drop. This could be exploited to make the Rift easier, and also allow players to swap around skills which is not supposed to be allowed in Greater Rifts. With the hotfix, monster health in a multiplayer Greater Rifts stays at the same high level even if some of them leave the game.

- Monster health now properly scales off of the number of players who open a Greater Rift, regardless of whether a player leaves the Rift or game. (10/24)
As noted by Nevalistis on Twitter, this did not change single player Greater Rifts, since those have always been locked in at the start. There were many reports of players using this exploit to make multiplayer Greater Rifts easier, however.
A hotfix went out on 10/24 and the list has been updated for @Diablo. Sorry for the delay! http://t.co/Wo0wLKI8bM pic.twitter.com/gFJiJhIBWp

.@altermaven @tanjon @muchgoodmojo @Diablo To be clear, this never impacted solo leaderboards. Leaderboard type locks at Greater Rift start.

This has been the first round of Greater Rifts in Diablo III. There will no doubt be more iteration for Seasons and Greater Rifts with Season 2, which we will likely hear about soon at BlizzCon 2014.
