World of Warcraft and Hearthstone get Heroes of the Storm cross-promotion items

Do you have any desire to play the newly launched Heroes of the Storm yet? What if we told you that you could get a free pet? Yes, Blizzard is running a cross-promotion with the newly launched title and two of its established online games, Hearthstone and World of Warcraft, awarding players shiny new things in one game for advancing with one of the others.

Players who reach level 100 in WoW will get a new mount to ride around in Heroes of the Storm; likewise, players who have won 100 matches in Hearthstone will get a different mount that will be available soon. On the flip side, World of Warcraft players get a pet for reaching player level 20 in Heroes of the Storm, and Hearthstone players get a new card back for reaching player level 12. Whichever of the group you play most often, you have the incentive to at least check the new title out.
