DK singular, use Heart Strike instead Blood Boil

is there a way to set dk singular class, to use heart strike on blood runes instead blood boil?

thanks

 

Afaik it uses Heart Strike if there are less than 4 mobs and blood boil if more or equal to 4 mobs around.

 

mine use blood boil in single target or 2 mobs.. everytime.. not moved anything in the tab settings, my dk is 59. any more info you need.. i can upload log too if you need too

 

im blood dk btw

 

still getting this issue Honorbuddy 2.0.0.5771,
