This is where we just aren't seeing it. The Paladin class is good IMO (and has always been powerful), but the archetypes are very bland. Maybe because they did focus on the White, Green, and Blank knight?
When people want to play a class, and are turned off fromt it because none of the archetypes appeal, that is an issue!
By your other comments, your group doesn't have a problem with the flavor, but the actual power level of the archetypes?
Because, in play, the power bump seems significant.
