Nothing is AFKable unless you are brave! Things happen that are unexpected. People get in your way with other toons, your toon goes chasing after a mob that gets stuck or begins to evade because it's too far away from its origin to fight but not far enough away to go back to its point of origin, or someone tries to chat with you and gets upset because you don't respond, or someone simply trains your character by tagging everything that you are about to attack. The list of things that could go wrong is endless. I've seen all of the things I just listed. If you want to bot AFK you take a calculated risk. I just don't care enough to sit and watch my bot the whole time. On the other hand, I do care enough that I will not walk away for more than thirty minutes at a time. I leave them running for several hours, but I check in every 20 to 30 minutes to see what's going on.
