About Vivi, she played a pretty important role in the development of the story and with this upcoming reverie, she will continue to play such a role. Besides, every character  in the world of One Piece is not uselesss, but it is used to make the world as complex as it is today. All characters developed throughout the series and will develop. Except for really side-lines characters. Vivi developed quite a lot, seeing the SH in action, their mentality, ways of dealing with stuff etc. I hope to see what she will be like now. Not a freaking child anymore. Also if you want one final piece of reason why she isn't useless. Boobs.
