I think the most important thing will be to save up either BP or AP and then blow a bunch of them in one event that you want to rank it. Don't try to do a little bit each event, but save up to go all-out in one event. If, that is, you prefer to rank high (like for a 6*) rather than accumulating a few smaller rewards regularly. (both are legit strategies)
