Where can I send suggestions for games?

We appreciate the time and energy people put into making suggestions for our current and future games. Our company policy, however, prevents us from accepting for review any unsolicited ideas. Often in our industry, an idea being submitted will be identical or similar to one already used by other companies, or already being independently developed by or for a company. Therefore, Blizzard Entertainment® has adopted the unalterable policy of refusing to accept or look at any unsolicited submissions or ideas. You can post your suggestions under the appropriate category in the most relevant game forum: Legacy, StarCraft II, or Diablo III, Hearthstone, Heroes of the Storm, World of Warcraft.
