Locked doors.
I don't know what the fascination is with Zenimax putting locked doors in their chapters, but Vvardenfell is grossly over-inflated with locked doors.
And I don't mean doors that you can lockpick. I mean doors that serve no purpose other than to be props. The doors that have big chains over the front with a giant padlock. Many of the canton doors in Vivec have them, many of the cities have them, but the grossest example of this is Balmora.
Balmora is such a big, expansive city, with a huge presence in TES:III. There was so much potential to make this city something special for the chapter. Zenimax could've put in a mage's guild/fighter's guild, more shops, more inns, made the canal boats travel points, added guild vendors that line the walkway next to the canal, filled the city with robbable homes...
What do they do instead?
One inn. A Redoran kinhouse that becomes permanently locked off after you complete the main quest of Balmora. And on the other side of the canal, literally 9-10 locked doors that serve absolutely no purpose beyond serving as places for an NPC to run into during a forgettable and tedious trailing quest.
ESO is constantly criticized for its lack of exploratory diversity and interesting places to see, and in the Vvardenfell chapter, they've decided to shoot themselves in the foot by trying to fool the playerbase into thinking a place is more expansive and detailed than it really is by introducing fake prop doors. -Both of the main cantons in Vivec have a multitude of these doors-.
So when people ask me, or others, why they don't find ESO as particularly fun or engaging as the main ES games, or even other MMOs, is how they trim off so much, but then introduce things that don't contribute to anything beyond the sink of time, like the trailing quest.
Maybe I'm alone in this view, but I just figured I should share my thoughts. I've been playing this game for years (Only recently got forum access...), and have sunk quite a bit of money into the game, so it disappoints me greatly to see these patterns of, for lack of a better term, laziness showing.
