-Edit- This discussion is focused on Racial Theme. This is not about effectiveness in gameplay, rather that it is a lackluster thematic and mechanical replacement for Weapon Masteries. The topic is about the removal of 1% Haste or Crit racials --
I don't see the point in keeping 1% secondary stat racials when they aren't doing anything to making each class seem any more iconic or diverse. It adds no gameplay, and is about as rewarding as the non-optimal gems in your set to keep a socket bonus.
I think if they are going the route of retuning racials, they should address it properly and add racials that actually provide a bit of gameplay. Even the 2% movement speed or 1% to primary stat racials that NE and Draenei are getting seem more interesting; but 1% haste to this class and 1% crit to that is nothing a Gem couldn't replicate.
The racials in question that I think should be removed are Human Spirit, Touch of Elune, Nimble Fingers and Arcane Acuity. They should be replaced with something less transparent than a 1% Haste/Crit boost, and with more theme tied to the races. Worgen and Goblins are possibly the exception, since Haste/Crit has been a thematic inclusion from the beginning.
