No sub but you do have to buy it, it is free until they decide it is 'fixed' whenever that will be. I went back to it recently and it has been improved MASSIVELY, but that doesn't mean it's good. They have fleshed out the content with quests and continue to add more, there was a decent event running as well., but it's still very lacking elsewhere
The social interaction is still COMPLETELY non existant, no one talks, it feels like a single player game without all the good points of single player games (story). The UI remains cumbersome, there has been no changes to the combat, dungeons are coming but wont help on their own.
The new devs seem to be enthusiastically taking the game in the right direction, I think the basis is there for it to be very good in a year or two, but it has no story at all, and right now does simply feel like a mindless grind to a max level with absolutely nothing to do once you are there.
Still plenty of people playing though.
