The Ashes of Outland expansion went live in Hearthstone merely a day and a half ago, but Blizzard Entertainment has already hit with the nerf hammer. Four Demon Hunter cards have been toned down to reduce the new class' early domination in the game, in an attempt to make the fight a bit more fair for other classes.

The following card balance changes have been made:

• Skull of Gul’dan – Mana cost increased from 5 to 6.

• Imprisoned Antaen – Mana cost increased from 5 to 6.

• Eye Beam – Outcast Mana cost increased from 0 to 1.

• Aldrachi Warblades – Durability decreased from 3 to 2.

These balance changes could just be the tip of the iceberg, however. On Twitter, Senior Game Designer Dean Ayala mentioned that the Hearthstone team is keeping an eye on Demon Hunters. Other balance changes to Demon Hunter cards may arrive as soon as next week.

Demon Hunters are being targeted in Hearthstone's Arena mode too. A few overperforming cards will be offered less, going forward:

• Chaos Nova

• Coilfang Warlord

• Command the Illidari

• Flamereaper

• Furious Felfin

• Glaivebound Adept

• Illidari Felblade

• Immolation Aura

• Metamorphosis

• Netherwalker

• Nethrandamus

• Priestess of Fury

• Skull of Gul'dan

• Twin Slice

• Umberwing
