If it's something really good I'd like to take maximum advantage of it. Certainly, it makes sense to poke at the event bosses if you're sitting at 3 RPs and no other bosses are around, but this is more a question of whether to sacrifice half a level per day by running event maps to try to spawn them myself instead of running 12-5. If it's dress/skill blooms that work for girls other than Star Lily, then I want to stockpile a crapton of silver, but if it's lvl 5 manyus I'll pass.
