Okay, not going to cry, not going to complain or whatnot, there's enough of those threads.
I know there's a certain way to go about your leves to have at least a decent amount avaiable, and call me lazy but i'd rather ask for assistance before commiting a lot of time researching given how people already did this so:
What are the best places to get leves at each level range? I don't want to level up by acquiring materials and grinding like that, i'd rather do it through leves for personal reasons.
