They are outstanding as Cleric/Rangers. My personal opinion is that like paladins, they're not very good. Their special abilities can be obtained elsewhere from another character class (or multi-class) and obtained much better. They are good atmosphere characters, however, and I rarely make up a party based on any powergaming reasons.
Try Cleric/Rangers if you haven't already. So much better than Fighter/Clerics (except Dwarven Fighter/Clerics that is).
