That may be true, but most players are unwilling to take a class with no good saves.
That's a good point, and I kinda wondered why they had Fort as their best save.
Dang, I'm really liking that idea now for the Hexblade-based paladin who deals out divine retribution instead of curses. Holy warriors aren't really my cup of tea, though. If someone else wants to run with that idea, be sure to post it.
