Well I've noticed that when botting that obviously it always follows the same waypoints, obviously since you added that node, but what if you could add a randomizer. Something like I select this node to be walked on and it will step on a tile within the radius of that one next time so that your path of walking isnt so repetative. A couple of people have called me out on botting because they saw me follow the same path.
Like this crappy drawing
- = pathway
[x] = node slected
Original Node
--------------[x] Same pathway always followed
Randomized node
----------
............ [x]-------- Randomized pathway within the 8 tile radius of where your node is.
