Hydrophobic enkis ...

The place where Serpent Gobbles live looks like some sort of ford though. So I believe it should be rather shallow. Unfortunately, it is not simple to define heights on a heightfield map very accurately.
I am not sure where this gap on BDRoad1 should be ... probably at the junction with the signpost where you can read which direction you need to follow?
It may be true that a rather completely visible road may help traveling, especially for newcomers. On Ojaroad1, this path would lead - from Hydlaa - around the small hills (passing the portal rock), then to the right along the Pool of Stealth, then further down the valley (which is rocky, therefore you won't see much sand on it), on to the Derghir village, a turn to the left, and up to the plateau where Jashoky sells food. But really ... does anyone use this long road? No, most will take shortcuts through the hills. There already exists a thread which discusses the creation of beattracks by travelers, according to their recorded positions...
And making the Explorers Outpost less laggy would mean to reduce the amount of items there. What a pity. It looked so homely...
