Guild Wars 2 is coming out with a new expansion and you can play the prologue, Bound by Blood, on September 17, 2019. It looks amazing(as pretty much all their content is).
Also if you buy Path of Fire you get Heart of Thorns free! It's a great time to get into the world of Guild Wars. I mean, it's always a great time to get into it, but at least you get a B1G1 on the expansions right now.
