I'd rather not see more aetherytes in the open world maps; however, I think the city shard being in zone with the market board makes a lot of sense and +1'd OP for that reason alone.

Maybe a compromise to those wanting even more instant travel is a one way aether gate like 1.0 had (from a gate you can travel to the zone's aetheryte but may not teleport to the gate itself). Anyway, the zones are not that big and adding more instant travel just makes everything feel smaller. You may argue you don't have to use them so ignore the people who care about scale, but you then do not understand people, people will generally do what is most effective even if it isn't the most enjoyable choice.
