Why would an NCO select the Warrant career path over the Officer career path?

This seems like an easy question.  The same reason why an NCO would choose to become a Warrant Officer instead of staying in the senior enlisted ranks.  If you enjoy the technical, operational side of your profession, which I do, then why not become a Warrant Officer?  If you become an O-Grade Commissioned Officer you are back to the first problem with remaining an NCO, you are no longer technical in your profession and your duties are more administrative where all you do is climb the chain of command.  O-Grade Officers have to hold staff positions and command positions which are common-core career paths that are branch immaterial.  As a Warrant Officer you are specialized in your career field and paid to do your job.  If an NCO is selected for OCS and wants to be a Signal or Engineer Officer he/she might end up with a commission as a Chemical Officer.  It seems like a gamble for something you will do the rest of your career.  If you want to be a jack of all trades and a master of none, then stay where you are at or become a Commissioned Officer.  If you want to remain hands-on, relevant, and a subject matter expert in the field of your choosing, then apply for Warrant Officer.  

The reason I became a Warrant Officer was for two reasons. The first was to remain technically competent, kind of hard to do in the Signal field as a Sr. NCO. The second was, if I do 20 years in the military, what not get a better retirement out of it? I can stay technically skilled, and prepped for life after the military and receive a better pay check when the time comes.

Many other Warrants have already expressed my reason for switching.  I loved being an NCO, training Soldiers and mentoring NCOs got me out of bed each morning.  The BS of the Army has turned being an NCO into a babysitting job though.  I fully comprehend and support a leader being responsible for the actions of those appointed beneath them, but there is a point when individual responsibility absolves that leader of not preventing it.  I saw that I had promoted myself out of the day-to-day leading of Soldiers and was now an administrator with babysitting privelages.  I chose to go Warrant Officer because I love my job, and this allows me to continue my job for years, but still to teach and mentor Soldiers and NCOs.  I'm mostly absolved of babysitting duty (I only have NCOs under me), which allows my NCOs to grow and make mistakes as they learn and develop.
