Ok, I used to be a paladin hater...this subclass is the only paladin I have ever played, and one of only two oaths that I've really ever liked! I love the tenets centering on loyalty to kindness and justice rather than a particular authority or temple.  The ambling rose paladin can participate in Grand Adventures but I love that tenets like No Destination but Justice keep their hearts and eyes on the common folk, and help remind parties about the problems that seem too mundane for many. It's a steal at $2 and I highly recommend trying it out!
