New player, here. I just realized this, so I'll ask since I'm not sure.

How often am I supposed to be buying Soul P from Advent Battles? It feels like just ranking up and getting Soul P that way will take forever. Are SR weapons worth getting? My weapon page has a bunch of no-limit-break SSR and SR gear, and I feel a maxed out atk SR would spruce it up, but a legendary soul would really help too.
