Yeah, what MariyaShidou said. Your TP points are limited, but if you really want to blow through a level range its worth it.

Oh also just a tip. at lvl 30 go to Limsa, there is a camp called BloodShore (pretty sure thats the name of it?) if you follow the road North and East out of the major city there you will come across it. Before you get to BloodShore, you will come across a little shack, with a bunch of NPCs standing around it and a little farm. on the North East Side of said shack there is a guy standing by a fire. talk to him. you will not have any more problems with places taking forever to get to

I didnt realize this until lvl 34 on my main came across it by accident. not saying exactly what it is, because it was a nice surprise for me as a new player
