General

1 Barrage, DS, ST, Demo, TL and SI. Generaly, a training build maxes DS first. I'd assume you'd get 10 Pirate's Revenge first or max Super Transformation, since both of them will help your training(With maxed PR, it's practicly a consistent buff if you use it properly), then Demo. After that, I'd assume DS(To spam outside of ST), EO(I heard it's going to be good for LHC) or MW(As another party buff). It is of note that 15 DS is 5 targets and 30 DS is 6 targets, otherwise it hits 4, so it may be worth considering before you go on a full fledged bossing build.
