I didnt like GW1 as a MMO, because clearly its not a MMO.

but that doesnt mean it didnt have some interesting concepts for Solo gameplay.

I like how players can escort around Hero units for party members in specially designed Instanced.

Well with this new trend of solo dungeons from the Chronicles, I wanted to suggest maybe a Escort Mission with Hero NPC Units like GW1 had, but with more interesting gameplay.

GW1's heroes and missions are like the evolution of Escort Quest we know of from older games like WoW which had them both in the persistent world and Instances.

but I believe Instanced Escort quest can be more interesting than their persistent counterpart due to the fact that developers dont have to worry about balancing the encounter around other random non expected things happening from outside influences.
