Black Mage, 2 methods I learned for rotation, which is superior for dps?

[Shiroe]

trasposing is slower, bit you cast a B4 + foul + possible filler, mp might just tick up, also since you have to hardcast f3, which is slower too..

I havent tried it out yet (since I cant pars eitherway, ps4...), but B4 has more potenvy than B3, even if you lose time hardcasting f3, you get an extra f4.

just curious if the rota really doest work (will there always be too little mp?), and by how much worse it is (or better??).., maybe the rota could work, but needs a standard start rota first (with B3) as an openet, to lay the track, so foul will be ready or something)

or is the main problem, not having enough mp for B4 after transposing? (waiting always to long?)... , talking about single target

(sry for the typos, using my mobile)
