Molten Core Fire Resistance One-Shots Adjusted - Season of Discovery Hotfixes

wowhead.com:

Blizzard has released a Hotfix for Season of Discovery, which allows players to exchange their 18-slot version of Bottomless Bag for the 20-slot version (Bottomless Bag), reduces the chance for players to be one-shot in Molten Core, and introduces several Class adjustments.

Molten Core Overview Guide — Season of Discovery

• Players who have the 18-slot version of the Bottomless Bag may now exchange the bag or the Pattern for the 20-slot version at Rix Xizzix in Booty Bay.
• Players who have killed Magmadar but are unable to douse the Rune of Kress can now swap the Heat difficulty back and forth and should find you can now douse the Rune.
• Lava Surgers in Molten Core will no longer spawn once Ragnaros has been defeated.
• Fixed an issue with many of the class dungeon set bonuses. They can now only be triggered by abilities, and not by item use.
• Ragnaros is no longer immune to Paladins' Hand of Reckoning.
• Fixed a bug interrupting eating or drinking when near a graveyard.
• Fixed a bug where the incorrect version of Quel'Serrar could appear in this version of the game.
• The increased damage taken for low Fire Resistance in Molten Core on Heat 2 and Heat 3 has been reduced but is still extremely dangerous. Characters who are at 30 resistance lower than intended should now expect to take about 3 times normal damage (was guaranteed fatal).
  
  Developers' notes: This is intended to allow players who are dependent on Resistance Totems or Paladin Auras to have a chance to survive if briefly not within the range of those effects.

• Entrapment now triggers a diminishing return as a Root effect on players each time it is applied. Subsequent durations will be halved and then quartered in duration, and then the target will become immune for 30 seconds.
• Fixed a bug that prevented Hunters from being able to interact with the four demons involved in the Rhok'delar quest chain.

• Fixed an issue where re-speccing did not remove Divine Spirit
