Hard agree. Especially Seitung could use a couple more waypoints. Anet has gotten seriously stingy with waypoints ever since POF. I mean, sure, part of it is because you can cover greater distances with your mounts, but even so it's too much sometimes.
That being said, re the whole Echovald vs Tangled Depths issue; I hate TD. Still haven't completed the map. Can't even travel a distance of 5 meters without getting completely lost. Echovald is nowhere near as bad. It's actually quite nice. A bit monotone perhaps, but not the worst map by far.
