The biggest tournament in the short eSports history of Blizzard’s Hearthstone: Heroes of Warcraft card game should have been a landmark moment for the game. Instead, the tournament’s final duel resulted in a controversial finish to the event. While RDU won the tournament with a 3-0 win over Amaz, the fans certainly weren’t happy with how the final played out.

The controversy came during the second match of their Best of 5 final. Rdu received some messages through Hearthstone’s chat function informing him of the contents of Amaz’s hand. He also received a few messages from friends that fans felt were coded messages to tell RDU which cards Amaz held.

After the second match, the final was delayed as DreamHack personnel were consulted for a ruling on the incident. They concluded that no action would be taken and the final would carry on with RDU still up 2-0. He would go on to win the next set and win the tournament.

While some people believe RDU won as a result of the messages from his friends, Amaz posted a video explaining his perspective on the matter stating that he believed that RDU was “definitely not cheating.” In a Facebook post, occasional Hearthstone pro and caster Artosis said that no pros believed that RDU was cheating and that the messages came at a point in time when RDU “definitely going to win no matter what.”

So RDU will get the win, though it will be tainted in the eyes of some. Perhaps Blizzard will learn a lesson from this incident and introduce some sort of eSports features into the game. Despite being featured in competition during 2013’s BlizzCon and having a featured championship tournament at this fall’s BlizzCon, no chat muting or spectator mode has been introduced to Hearthstone. Hopefully this spurs Blizzard to action.
