Bot? You mean like opening the console, typing mousefire(1);, and looking at an automatically respawning resource?
Perhaps someone can make a fancier one that automatically turns to face other resources, and once in a while strafes just to throw off automatic bot detectors.
Why not reduce grinding by giving a harvest bonus for each skill type, reducing the time to gather, but that bonus decays as you use it, eventually making gathering take next to forever? That way, if you switch between resource types once in a while, you actually progress faster, while simply grinding one skill causes resource and skill gain to literally grind to a halt after a while?
Or, you know, fundamentally redesign the resource system; that would fix botting too...
