I'd love it if there's a plugin that will keep honorbuddy from randomly making incredibly sharp corners. That way it'd be way less obvious that you're botting.
HB3 navigation will get calculated server-side so what a plugin could do, is trying to jump in whenever a new hotspot is set and trying to smooth it out. I assume this could be a rather unpleasant as performance might get reduced a lot as this plugin will have to listen each tick for a new hotspot and calculating an alternative path/adding movement to smooth out edges.
