The point is it's a needless mechanic that does nothing but make an already tedious part of the game more tedious. You are going to get where you are wanting to go anyway, so why make you get there slower? It doesn't offer a challenge, it doesn't make the game more interesting, it doesn't add anything to the experience of gathering these nodes in a positive way. Obviously some don't seem to agree so I'll leave it at that. Thanks for voicing your opinions.
