Im having some trouble understanding how the BiB system works. What build does the BiB system use for a frost dk. During raids I use breath of sindragosa build and it was to my understanding that mastery had more priority over haste but the BiB system gives me haste over mastery. The breath build also uses the legendary, ‘seal of necrofantasia’ as a staple of sorts aswell but the BiB system does not suggest it as the best option…how does the BiB system work!!
