I'll be honest, Pointy Hat lost me by saying the old-school LG Paladins made role-playing predictable and tedious. As someone who started playing paladins forty years ago, I can say that they have never been necessarily predictable or tedious. They're like the role-playing equivalent of a sonnet; they're a chance to express creativity through the focus of limitations.
It will be interesting to see how they implement 5E paladins in the full game as the tabletop version turned me almost completely off what had been my favorite class. I think part of the problem for me is that while more player choice is a great thing, the increased freedom changes the nature of the game. Some of the changes work really well, others remove some of my favorite aspects of a character type.
