I probably not going to be the most liked person here but if you are going to clean up the Harbor and make it more New Player Friendly, let's truly clean up the harbor.
Currently you have new players running willy-nilly about the harbor with no real sense of direction. The idea of a harbor clean up and rework is great but it doesn't address the problem od new players running around willy-nilly without sense of purpose. I like the idea that you start on one side of the harbor and quests have been moved about, but I don't feel it goes far enough o help the new players. Cluster the quests in order by level allowing players to move fairly quickly and "automatically" between spots. Make sure their is a general vendor and low level potion vendor in each cluster. In the old days we used to railroad new players until they reached level 4 or there about now even in the new layout it easy to get distracted and off ... squirrel.
I would move the quests formally located in Aspirant's Corner (they were "Home Sweet Sewer", "The Miller's Deb" and the quests released with Module 1, Patch 3 - "An Explosive Situation", "Arachnaphobia", and "Home Sweet Sewer" (all originally solo quests)) to Korthos Village and reset them as level 1 quests.
I would continue by moving the entrance to "Information is Key" to where "Retrieve the Stolen Goods" was formally located.
Move the entrance to "Bringing the Light" to somewhere in the same vicinity.
Move the entrance of "Recovering the Lost Tome" to where "Fear Factory" or even where the old entrance to the lobster is currently located.
Move "Durk's got a secret", "Missing in Action" and "The Sunken Sewer" to location near "Garrison's Missing Pack" Yes I am advocating moving some of the quests entrances out of the Marketplace.
Move the vendors out onto the patio of Hammer and Chain and Dagoward's Apothecary no reason for those instances to exist anymore.
Move the entrance to "Redfang" where "An Explosive Situation" is currently located.
Move " Kobold Assault" to where the new location for "Irestone Inlet" is.
Move the entrance to "Fear Factory", "Sinister Storage", and "In the flesh" to the vicinity around where missing and "Invaders" is located.
I am sure there are others that could be moved to simplify the path. But please don't just "kind of" make changes do it the entire way.
I really like the fact there is movement behind the gates (maybe removing the gates between Harbor and Marketplace is coming).
