Difference between holy knight and sword saint?

[Fatal Rose]

From the brief look I took Sword Saint and Holy Knight feel like vastly different classes. If you wanted to play a Sword Saint, play a Sword Saint- if you wanted to be a healy tank with varying degrees of damage output, play a Holy Knight (Smite Evil is pretty awesome).

The few abilities that do share names aren't really enough to make them the same class- Sword Saint looks fun but is very much a combat class while Holy Knight is Combat/Support.

Thanks.

I'm addicted to this site. My current DM won't allow us to play any of these classes. He says he's not familiar enough. Need to find someone open minded. Difficult to while living/teaching in china.
