PvE Focused gamer considering returing.
I would probably advise you to start dungeons when you are a higher level than the requirement. Almost every dungeon run I ever had was pretty smooth….but it’s only because I stopped trying to do them as soon as they are available :P
As a result this became what I would call ‘endgame’ – running the dungeons to the best of my ability at 80, and along the way picking up some rewards that are even awesome at max level. When I was 35 with my Thief, all I can remember doing is map completions + dailies for fast leveling, and constantly respeccing/traiting to explore the class. I’d recommend you do the same, because yeah, you do get your butt kind of handed to you when you have entry level gear + minimum level. It doesn’t bode well for Thieves that they’re one of the squishier classes, either.
The whole content thing is a matter of opinion, really. I’m 800 hours in though, and still going strong since release
