I keep reading all these fucking posts trying to justify pulling or not pulling Cerydra based on her gameplay and I'm like, bro. Just pull her if you like her and don't pull her if you don't. If you're pulling a character you don't like just because it's useful, you're playing the game wrong.
I like her a lot so I pulled her and I'm happy. Mind you I would have skipped her if I had lost the coinflip because I'm F2P and can only afford so many characters, but I didn't so I have her, and still easily have enough for two more characters. After which point I'm bone dry so hopefully it doesn't take me all the way to hard pity and I get some breathing room, but even if it did, whatever. Gacha games are not difficult, especially when you've been building your existing characters for 2.5 years. That's why it's always about the character, not the gameplay.
