it's ok to not like something, but, I think you should remember;
Daisy is an echo, which is the same as Lucina and Dark Pit, which were all late addition's to the roster, and most likely Daisy was too.
All characters are as of now completed, or near completion, with balancing, and finale touches being brought upon them. The way they revealed Daisy was genious, as they made it so that we knew she did not take up developement time, and is a late addition, just like every other clone. Daisy fans just got their biggest wish true, and I'm really happy for them. Daisy is no issue at all when it comes to Smash, and she certantly deserves it.
But, as I said, it's ok to not like something, it's in your right.
