Well he won't help you in this case.
As for your 'faith' in streamers, you are aware that Blizzard has builds that are further developed than the 'public' or testers in this case or your faithful streamers can actually experience don't you?
It seems from your post that this isn't the case and that your cherished streamers and you have no clue.
Point being: that they are further along than people think.
Or see for that matter.
Or able to test.
For all we know they could be 10's of builds ahead.
If folks think that what the alpha testers are testing right now is also what Blizzard has available to them internally then go ahead and claim otherwise.
Without proof.
