Are you referring to the 5F4 rotation that doesn't need umbral hearts?
Yeah i mean 5xf4 rotation (which is techically 4.05 rotation because 4.0 rotation was 4xf4). There's no really any reason to use b4 outside of opener or when foul is on cd during umbral phase but mana is not ticking fast enough to just cast single t3 and switch.
