I disagree with the 2 comments above. It would not be obvious this is a bot. Tons of people already do this and have since release night. Create a bot that joins the public games and just alternates between running to stash, blacksmith, jeweler, and enchanter. Would look like somebody just checking their gear.
I can't count the number of times i've been in full public games but only 2-3 of us are doing the work while the others just stay behind collecting shards and quest xp.
But, as a bot. if it got popular it would be garbage because this is all you would see and the bot would effectively cancel itself out.
