I used Minotaur at one floor at tower. My union mate (same one that actually told me about whole strategy) used wind cut eido against wind present rag when he didn't have enough power to finish it other way (or so he has said). One uses things that work best in some situation, as popular saying goes: "if something looks stupid but works, it ain't stupid".
That narrow window is the whole point here. Nobody argues here that some strategy is best for everyone and anyone in all situations. Existence of that narrow window should remind you that there exist Souls other than Hercules and Shingen.
