The single best ease of use that can possibly be implemented is simply moving the Central Brittany icon on the overland map away from the bridges. Disclaimer: IMO.
Why is that? I rarely go to Aerie or Brittany due to lag, and no real reason to be in either place. Between Aerie and Owl's Head, I seem to find all the recipes and recipe ingredients I need. I also have my own teleporter to Owl's Head now, so I never need to leave the longfall region. Though, Aerie is also a bit laggy! I like it better than the other "regional capitols" though.
Well, I assumed that most people would try to use the bridges behind the Central Brittany icon on the world map. I guess I was wrong and my apologies. The problem is that to get across the bridges requires a jog around the city and the oracle building. It is an obstruction that does not need to be there IMO. This has nothing to do with lag.
Oh, thanks for clarifying I thought you were referring to something inside the scene. I do sometimes run through there to get to Drachvald and Grunvald. Ill pay attention to what its like, I might have unconsciously been navigating around it for years.
