Personally, I recommend that you wait until they get the bot working before you pay for it. It's been down for over two weeks and even the lead devs can't get the thing to run for more than 30 minutes at a time. They don't seem to know how to fix the HonorBuddy bot right now, and it makes me wonder if they will ever get it right again. It was a great bot when it worked, but it is presently the worst bot on the market. It doesn't do hardly any of the things it did before patch 5.0.4 The forums have been over run with complaints, and the Bossland devs seem to be getting their butts kicked by Blizzard's latest patch. I'm wondering if perhaps Bossland should quit selling HonorBuddy until they know for sure that they will be able to fix it. They said they would have it up within a week, but it's been over two weeks, and it is still broken. Obviously, they don't know how long it might take. It might take forever.
So, my advice is wait and see.
The dev's statement mentioned above is at the top of the thread linked below:
[OFFICIAL][Patch 5.0.4] Honorbuddy will be offline a few days more
For proof that the bot is still broken see almost any other thread on thebuddyforum.com under honorbuddy and you will read members' multiple complaints.
