i use HB for over 6 monthes, and i still dont know how to use head only. therefore, i use HB for only daily quest and 30 win for 100 gold on rank 20.
This does make the bot more aggresive vs opponents hp but still attacks opponents creatures alot. And changing the value of opponent hp to a alot will make the bot play weapons before creatures. They should include an option like "bool tryFaceOnly = true;" or something that we can change.
I haven't used it for 6 months, but I use Hearthbuddy for the same exact purpose to earn all the daily gold. Things like solo, tavern, and arena I do on my own.
