What server should I transfer to?

I'm a level 30 dragoon though, I wouldn't wanna go through all that again I rather just pay the 18 bucks and have fun

Alright, that's your choice. You've made up your mind but I recommend you try searching around on Google and whatnot about population information. If you have some friends, perhaps you should see what server they plan on and join them? There's a lot of factors. I started on a JP server because I have friends there.

It's really going to be your choice, but perhaps you can look over the Free Company recruitments and start some talks there. I am assuming you want to make a lasting decision.
