Y'all is redundant. It's trying to bring back functionality to the English language that has been lost.
You could make the same argument about "youz guys" or many other colloquial terms. It's just a regional speech pattern. Like it or not, grammatically correct or not, it's been part of the vocabulary for a couple centuries and likely will continue for a couple more centuries.
