Valentine Chelsea's story kind of sold me on her, so I sparked her. It helps that I need more solid wind DPS and she's limited, and I still have enough for two more sparks (maybe three if I read all of the stories available to me), so I should be okay. The pulls along the way was rough though. For new adventurers I got Nevin (which I'll likely never use) and a ton of dupes. Not even a Valentine Melody to lessen the blow. For dragons, duplicates of Apollo, Zephyr, G&C (this oneI don't mind, I'll work on MUB'ing a second as it's basically a gala dragon), Nidhogg, Chthonius and Midgard 0. For new ones I got two of the new dragon (who doesn't seem the best unfortunately), Azazel (can use him on Grace) and a Kagutsuchi. I'll probably only be using the G&C and Azazel, but hey...more dragon stories! And another unbind for my Midgard 0.
But you know what? At the end of the day, it's a gacha game and we really don't know the future holds for it (as well as us all), so I'm just going to enjoy myself as much as I can. I'll save a spark (or two, if I suspect a collaboration is near) for a character I REALLY need, but aside from that I'm just going to enjoy myself.
