I playtested it, too, and the class just felt bad to play. It was by far the most unpleasant experience I have ever had in 5e in any form, and I've played a 2014 Four Elements Monk. I was juggling bonus actions too many times, and at no point did a smite ever feel like an option at all. Simply dual-wielding is a better use of my bonus action, and other classes are better at that, too, because the one reason to dual-wield on a Paladin doesn't exist anymore. And when a smite isn't an option, then I might as well play another class.
