Welcome to the Weekly Question Post on c/guildwars2!
This post is dedicated to those questions that you might not think is worth making a whole post about, but sure is worth getting an answer to ;)
Remember to also take a look at the links in the sidebar, which holds lots of great resources and information.
To add to the other comment, ascended also drop in fractals quite often and you can also buy them there.
Can recommend joining a guild that runs guild missions, since you can buy some in the hall for the currency you earn from those.
