I still have no idea what to pick, help me decide.
For W-Engines I don't have Brimstone, Hellfire Gears and Steel Cushion.
For the characters I already have M0 Grace, M2 Rina, M2 Koleda, M2 Soldier 11, M1 Lycaon (I lose a LOT of 50/50s)
I'm thinking of picking either Brimstone or Hellfire gears for the W-engine and Rina for the character since I'm using her the most out of all the standard S-rank characters.
