Should the Air Force bring back Warrant Officers?

First some background, the U.S. Air Force stopped producing Warrant Officers approximately four decades ago; in light of upcoming force structure changes, do you think that it is realistic to them back? If so, what are some of the associated pros and cons to consider? Has the Air Force suffered, is it better off... or does it even matter? The idea here is to begin an inter-service discussion on the merits of Warrant Officers in the AF, and in light of reducing budgets and change throughout the ranks, do we need to consider bringing them back? There's no right or wrong answers here, just an informed discussion on possibilities and precedents. I look forward to hearing your thoughts, so pull up a keyboard and let's get this thing started, thanks for all that you do, and... see you all in the discussion threads!
