from what i experienced so far while farming dark lord for the last two days: just farming dark lord cuts off a lot of exp, just did a normal pvp battle for the first time and was kinda shocked how much exp you get for only 1 fight (at half the cost). i think i would have made MUCH more progress if i did more pvp battles, leveled up faster and used the energy on the story campaign. but on the other side, i made lots of money due to rare dark lord drops and gacha so all my girls (7 in total) are affection rank 3/4, and bunny already reached rank 4.

in the end, i'd do it again like this, now im going to level up, earn the free enrgy and "save the princess" *cough*
