This propably doesn’t have the highest priority right know but i often find myself trying to jump down/up somewhere when i bump into invisible walls. While it is possible sometimes to jump down certain cliffs most of the time it isn’t.
I often find it frustrating to try and jump over a small fence for example only to be blocked by an invisibale wall.
Most maps could feel al lot more open/refined if there were less of those insvisible walls (i hate those).
To showcase what i mean i made an album with a lot of screenshots showing all the spots that could be improved on the map Seir Rainforest: http://imgur.com/a/ApM1c
