Monitor the bot while levleing, when he is at certain quest that he fucks up - stop it and do it by hand.
I've leveled 3 toons, with several hours to a day difference in the progress one from another.
Wherever the bot failed hard - like stacked in a tree, or stacked at some door trying to get in mounted(he just have ti dismount, but...) or he stays infront of the quest object and watches it doing nothing, or the hotspots written by Kick were terrible and the mobs that have to be killed are in different place(this was 1-2 quests) - I've taken control over the bot to finish the quest by hand.
