Ahhhhhhhh.....an honest FO! I knew there was one out there!
A lot of my NFO buddies are quite open about the fact that they wanted to be a Pilot and didn't get it for whatever reason. I'm in an ECMO-cantric community, where pretty often the double-anchor guy is calling the shots, yet you still have a lot of guys who want/wanted to be a pilot. The only annoying ones are those who constantly want to talk about their sob story, even years later.
I wanted to be a Giraffe when I was young. Sometimes things don't work out and you move on.
As for whether or not a recruiter would look down on you for putting NFO only, I will call BS ont that one. I didn't put NFO or ground and I got what I wanted. I have heard that whole, "Be a team player and you will probably have a better chance of getting what you want" thing before. I didn't but into it. When did it become a bad thing to know what you want to do with your life?
I would say put what you want and don't let bitter people get in your way or you will become one.
