Thanks again for the replies! I just hit 19 on my Marauder and my gear is all tanky so far. It's fun. Started leveling Gladiator and Pugilist to get some synergy going. (my god they attack fast, marauder is so slow I had no idea!)

It sounds like for the end-game I should plan on Warrior specific left-side and probably 2 sets of trinkets. Looking forward to the journey.
