Well, it's actually not a difficult thing to decide whether we love Dolores as a solo or not cos it is buried deeply in our soul. But the reason why we are discussing now is that there are different kinds of Cranfans, and the whole solo thing is thus not simple at all. 
I fell in love with the Crans cos first of all I like Dolores voice, at the same time I can't deny the importance of the other three members of the band, cos it was they who gave her voice a unique and incomparable enviorement to live and grow. And the myth of the band lies also in the special position of Dolores, she functioned as the girl who was supported by three male musicians, so her coolness and experimental flairs is best underlined.
Now Dolores is going solo, and we can't help worrying that the power and affections of her songs will be weakened. There will be no band, no one play behind her and beside her. Our whole concentration is on her now, will she fulfill our fans' require and desire by herself, or are we expecting too much from her? 
Of course we love her voice! But sometimes voice is not the only determinate factor of music! We are expecting a more confident and a new Dolores O'Riordan.That's a turning point in her career, and we'll go with her as far as we can/will.
