This botbase is screaming for a follow range and a wander range. Two separate values. Currently as it stands, the way to make the bot look the least like a bot, is to play it off like it is a dualbox setup. The problem with this if you set the follow range to mimic a dualbox setup, the bot will try to loot outside of the follow range and run back and forth in tight circles.
A follow range and a wander range would fix this. Allowing the bot to move X number of yards from the leader when doing things like interacting with a target (quests/looting) and then a follow range that the bot will try to achieve when it is not grabbing/turning in quests or looting.
