Thread about the production quality blew up.

But the thread about James 2GD Harding being dropped from casting skyrocketed.

The news about the dropped caster only just dropped and so the drama is still developing. Expect more when Steam releases a statement.

Edit: This has been Twitch chat for literally the last hour.

The whole front page of the /r/Dota2 subreddit is full of threads about it.
