While I wait for this Wednesday Maintenance (so much for the above times ;-) I read the 1.05 patch notes and noticed a detail that I (and undoubtly others) suggested in feed-backs:

It is important because it will essentially eliminate the benefits for gold-farmers to parking 4-5 bots at the spawn site of every public dungeon boss and automatically killing it as soon as it appears. I have seen many of those since the game launched and I was getting tired of reporting FFFFOOO, XXXXILLI and their friends for use of third-party unauthorized software.
