Tentative Heroes List
Through datamining, we have determined that the following heroes are either on their way to the Nexus, or were previously in the game and have been removed. Heroes below are ranked on how likely they are to be in the game based on data available to us in the client. This list is not guaranteed to be an accurate representation of the final game.
Hero Art displayed in this post is not from the game client as these heroes do not have portraits. It is also worth noting that some of these heroes have been previously seen at BlizzCon.
These heroes have multiple references to voices and character data.
The character and voice data for these heroes is not as refined, but it exists.
Missing Hero Data
These heroes have voiceovers, but lack data which allow them to be selected as heroes.
There are very few references to these heroes, but at least there's something!
