Hmmm...
Try getting smooth movement, not the jittery walking-into-every-single-tree like movement.
Ive watched a BUNCH of Glider movies and tried the demo, the major failure tehre is the movement.
Also get some filtering on wich mobs to kill, what to loot, and maybe even sell to vendor action.
To get it a A++ you could even merge it with a fishing bot =)
Hope this is some ideas (even tho i know it wont help much)
