Blizzard has announced during today's Warcraft 30th Anniversary Direct that Hearthstone's Arena is getting an overhaul.

  • There will now be two modes for arena.
  • Normal Arena lets you play the more typical arena run with a shorter format. "Awesome competitive experience."
  • A new mode, the Underground Arena, is available after your normal run and adds high stakes card play.
  • Underground Arena has longer runs and allows you to edit your deck after a loss by redrafting cards to up your chances of winning.
  • Arena Ratings will be available for normal and underground modes, with separate rankings.

The updated Arena will appear in the first half of next year.
