You could be correct, I was meaning specifically so you develop the muscle memory, I don't do under level 50 content anymore with my BLM (haven't for almost a year) so I'm just theorycrafting. Maybe even badly. That said, by now you should be pretty close to 50! In the end the up to 50 rotation is not super important because once you get to 50 you will never need to use it.
The main difference between going B3-F3 versus transpose-F3 is that you are guaranteed a mana tick by hard casting F3, but now that I think about it, it sounds straight up worse to transpose if you don't have Flare. Oops.
