Currently on live the Basalt-Blooded Warrior set does not properly swap stances if it is being used on only a single bar. Using it on your primary bar and swapping to a secondary bar that has a different set will leave the Major Heroism running as is. Conversely, using it on your secondary bar will provide the healing and shield buffs to both bars as long as the set is not also equipped to the primary bar. If both bars are equipped with the set it functions as intended.
