I don't get why you're being downvoted. I write Go professionally and I've been doing all of my work in Go for 2 years. I used Sublime/vim/emacs, and I'm very productive without an IDE.
Still, there are many features of IDE's I wish we had, like extensive refactoring. I was making heavy use of those in Java.
It's very easy to write software that manipulates Go code, so I know it's just a matter of time before all those equivalent (and more!) tools get out. So much that I feel a lot more productive in Go today than I ever was in another language before. Go works really well without an IDE, but just imagine how much more you could get done with an environment that ships out of the box with comprehensive tooling for refactoring, debugging, profiling, etc.
I think it's counter productive to not acknowledge, or be dismissive, of what comprehensive IDE support can provide to your productivity in a stack. Tooling in Go is awesome, but there are gaps. Debuggers and more-than-gorename refactorings are to big bullet points in my personal list.
[edit]: OP was being downvoted when I wrote this.
