I understand why they exist and why they have to be set on many places.
But sometimes, they just ruin the fun for the explorers. See that peak over there? It would be nice to climb it? Right?! You can't - even though terrain exists, everything is there. But yeah. The wall.
See that cliff over here? Nice view, probably, but you cannot go. Again.
Invisi-walls are effectively even more annoying in the houses when they prevent owners to build a 2nd floor in some higher houses or to go slightly off in the wild. Sometimes owners use various "hacks" to do that. Just like some know a "hack" to climb Red Mountain and other places. But that's very off the charts and I understand why invisi walls are there. Still it's fun.
My question for
@ZOS_GinaBruno designers - why do you hide your beautiful work behind those walls in unneeded places?
Elder Scrolls games are all about exploring, discovering and going off the path. Invisible walls effectively prevent you to do that. And I've seen so much detailed world out there, in ESO, that was made to be hidden behind those walls.
