Guild wars 2 in 2018

So I am looking for a new MMO to become addicted too, and gw2 seems to be one of the most popular MMOs out currently even though it is very old. I am coming from BDO, which is riddled with rng, p2w, disgusting amounts of grind, and afk activities. Is there anything like that in GW2? I want a casual experience that isn't like working a second job. Also, what edition should I get? Assuming I like the game in f2p, should I go ahead and get path of fire since it's the latest expansion, or should I get all of the expansions? Thanks in advance for the help.
