I don't understand what you're complaining about. Mine charges in 5-6 hours from 0-100. Using iPad 1 dock and iPad 3 charger. It was never fast, and it doesn't feel any slower now.
Remember when the iPad 3 first came out, all the negative reviews/blogs due to it heating up and "taking forever to charge". I don't see a single complaint any more. It charges fast and doesn't burn my hands.
