I'd you should give it a shot.
@Akiho isn't wrong... you probably will never find that nostalgia you have from 10-15-20 years ago but the game is still entertaining and there is plenty to do. That said, if you don't mind the 10-13$ a month to play why not come back and give it a try? I'd suggest ATL if you really are looking for a consistent group of people as there are several big guilds like KOOL / LLTS / OSG etc that often do group hunts and play as a team. If you go this route though, I'd suggest accepting free gear and scrolls to get up and running ASAP because there aren't many "newbie guilds" where it's basically just a bunch of people starting from scratch and helping each other level up.... most of the big guilds are established players and do things like Shadowguard which will require more than 75 magery/eval to contribute to.
Worst case scenario - after 2 months if it's boring or nobody is ever on then just cancel the sub. No harm no foul.
If you decide to come back and pick ATL let me know and I can give you some gear to get started.
