There's nothing wrong with the rotation. If you're worried about BoTD falling off, just use GK less. You can play it safe while learning fights, and once you are confident with the fight and know the mechanics and their timings, you can use GK more often in a way that doesn't make BoTD not drop off. I personally use 90% of the rotation like normal in Ravana Ex, and only save the occasional GK based on downtime (e.g. running from orbs) or so I can shift them a few seconds away so I can use more in a red phase instead.
