I have no issues using purifing brew manually after the first fat shield with it since that is really something i feel better off managing myself anyway.
spinning crane kick i do manually as well but yeah putting it on a modified works too but the macro doesnt prevent you from going into spinning crane kick while its running so i dont see a need for a modifier.
Im pretty sure that eye of the tiger is better in ALMOST all situations (in practice) then chi wave. Chi burst could be better in AOE but you’'d have to manually choose when to use it.
