Kaozz has a great post at ECTmmo on games that have non-combat activities to give respite from the endless slaying. This is particularly well-timed given that so many gamers are currently spending hours in non-stop slaying binges in Diable 3. I agree with the premise that MMOs, especially the latest batch, are far too focused on combat, Rift and SWTOR are two examples of this. It’s not as though there aren’t entire genres of games devoted to combat, offline and online. Open world MMORPGs therefore should offer something else to do besides.
My current two favourite games, in this regard, are Vanguard and EQ2, both traditional fantasy themepark MMOs you might say. But they have very rich settings with specific non-combat classes to level.
If LoTRO had better housing I would add LoTRO nearer the top of the list as well as the Shire is such a great non-combat area and the farming is an unique and very enjoyable crafting profession!
