I'm a bit of a character collector, I saved 3 pumpkins Warrior, Sentinel, Magis from last years halloween event and have acquired both the Assasin and Gunner this event, having exhausted all other souls and this being such an epic event I'm very tempted to chuck them in. Their all 5* maxed, but I'll never use them and can kind of justify not having them as part of the regular collection... should I or shouldn't I?
