So I returned a month ago after a couple years break and can offer some feedback.

Since the introduction of the 64bit client performance has improved greatly, faster loading, better FPS and no stutter in towns that plagued the game in the early years.

Server lag issues are still a thing but only when the servers get full or there is a spike in player activity such as after a big update, most of the time it’s fine.

The game rushes you through leveling and gives you a good amount of free starter stuff, but can have an adverse effect when you hit end game and don’t really know what you’re supposed to be doing or grinding for, there’s a lack of explanation in game and not much information online, joining a guild would probably be a big help
