Hearthstone’s Grim Patron meets a grim fate on the eve of BlizzCon

Blizzard notified players via a post on its official forums this morning that it’s modifying the Warsong Commander — the lynchpin of the immensely successful Grim Patron deck archetype that has defined the metagame in the pro Hearthstone: Heroes of Warcraft scene for the nearly six months since the deck concept’s inception.

The timing could not be more significant, as this news comes only two weeks prior to the beginning of the Hearthstone World Championship finals, whose first rounds begin October 28.
