In my opinion, a better mmo has the story as an instance that has co-op. Or what ever possible interesting online modes for small groups of a different faction.
However, the mmo part is all horizontal progression.
I say this because, i would like to see an improvement in mmo story, and bring the benefits of mmo development as well.
For example, the mmo part might have a mini game which would be part of the class quest. Or a dungeon which can be done by groups in the mmo or solo for special rewards etc.
So do people really want everything to be mashed up together? As stated it makes class story worse, and content segregated by areas and lvls to repetitive and not challenging.
Or is the future of ai/npc improvement going to change and make up for some of the short comings of the past? We still need better tech, and single players manage to implement those extra features.
