When the Little Ladies' Day event had more substance and the Succubus was a better overall mini-boss, I don't think people are wrong to complain. I won't lose sleep over it but I will say I'd rather they not bother at all if this is what the end result ends up being. Or at least be honest about it. They kept the whole thing a mystery and implied it would be more than what it was. That's why everyone was riled up.
