Pretty much all HB users leveling their characters 85-90 are doing it through battlegrounds due to the bot's inability to complete vehicle quests and the like (honestly, this should have been implemented years ago). The hilarious amount of bots in battlegrounds now reveals a few weaknesses with the profiles. I could name many but the main issue now is there needs to be a larger number of (or completely random) startup routines. As of now the bots kind of form a large glob in the beginning and run around together in a large hoard of bots until dying off. It makes Honorbuddy painfully obvious to everyone else and the bot much more easily reportable. Luckily right now Blizzard seems content to let a lot of stuff get by. As such the devs seem to have been resting on their laurels for quite a while... but since Bossland GmbH is a German company and German's are supposed to take pride in their work, I'd say the job isn't done.
