I hadn’t spotted this until snipeattacker pointed it out in the forums, an option to download the “public test” and to “play public test”. They have been there for a while but the Download Public Test link was not active and is now, even if it does only take you to Battle.Net at the moment.
So what does this mean? Well it looks like Blizzard are finally going to put up a test version of the game for future changes. This is common in MMOs where you have a separate version of the client which lets you check out changes before they go live.
With PvP still to come, this new addition could be to test the game’s PvP to get feedback, it could also mean that before any big changes go live in a patch they will look for feedback before finalising a patch. If this is the case then it’s great news for players. Right now the download link goes to Battle.Net but I’m sure we’ll hear more about this in the coming days, and funnily enough, this was discussed by the team in the last podcast.
