would suspect this or something like it has probably been suggested before, but here goes anyway.
How about some (drumroll) Adventures Between the Adventures? Epilogues to the Personal Story. Sidesteps on the Pathway of Life. Uh. You get cheap gw2 gold. Set in our characters’ back yards, so to speak.
These stories/quests wouldn’t have to be anything particularly innovative or fancy, no need for epic boss fights or dungeon-worthy team coordination, just plain old simple quests that offer a way for our characters to have more interaction with friends and family and associates from their Personal Stories and adventures abroad.
For humans, we might have some adventures with our character’s sister, or those circus guys, or maybe we could follow up on corruption in the Seraph. For asura, we might do wild and crazy experiments with our krewe. For charr, we might get out in the field again with our warband. And so on, and so forth.
For new characters, these quests could become available as the character progresses. Ideally, they could scale with the character’s level.
For advanced characters, some of these quests might be presented in the form of flashbacks, and some might be all-new, all-different adventures featuring the above-mentioned friends, families, etc., that may range far and wide but still be tied to what’s happening ‘at home’.
More stories/quests could be added periodically. Throw in some achievements/titles, of course. These stories/quests could also provide various and sundry personal touches to the home instances, maybe in the form of changes to various buildings, NPCs coming and going or getting married or taking up knitting or whatever. For example, maybe an outcast tengu you found sleeping in an alley could, with your help, fulfill his dream of opening his own shoe store, and become a permanent resident in your home instance.
