the problem with dungeoneering is, the fastest way to train it requires you to be able to communicate well with your team-mates and know how to set up paths and key fast
-- I have seen a team that got 5.5m+ xp in a day averaging 24 minutes a large floor which would be impossible for a bot
so sure, there will eventually be bots out there, but they will only be able to do solo meds and be slow and steady xp, which probably not be worth it considering that the bots will be complicated and expensive.
