If you're using vision a.i., and not specify the deck's config file set, by default bot may use [aggro] config set, this config set will make bot attack enemy hero aggressively.
You can set it to use [default] config set, then bot will be more control style.
You can read vision a.i.'s online help to know how to do it.
