With MP draining you had to pay attention to how often you were using DA SE before. Now, not so much. It's the same potency whether you're using DA SS, DA SE, or DA both. It's just about where it is in the fight. If you end the fight at 100 MP, and you DA'd as much as you could, it doesn't change anything. Now if SS had a bit less potency boost but the additional effect from DA was +120 pot and maybe +15/20 additional MP drained then we'd have to make a choice based on the phase/length of the fight. Is it long enough to get another DA worth of MP? Etc. Just ways to change it up a little so it isn't brain dead. As it stands now... it's use DA as much as you can on any skill since it's all the same potency increase until the fight is over. 1-2-DA3 and repeat until MP is depleted. You need NO DA SS's if DA SE spam is enough to run your MP dry by fights end.
