With the steam release coming up, I think it is a perfect opportunity for Anet to make some quick changes.
While revamping dungeons might be a lot of work, the rewards should be easy to upgrade.
For example: Adding a token of Accession - deadly blossom, would allow that gear to be upgraded.
It could cost 750 and would could help to revitalize the dungeons in the game and be a nice way for both new and old players to get back into them.
The only restriction they should put is that all explore modes are LVL 80 only.
Ascended gear is already given away like candy these days so why not just add it to the dungeon vendor as well?
Dungeons are for a lot of people a walk in the park but for new players, they can be a good middle-ground.
I personally do not see the issue with adding this kind of token, it would only revitalize a part of the game. It might not have the biggest impact but it would be nice to see more groups again doing this content
