Well, we've established you're not a Paladin, that's for darn sure. Lucky for those children you weren't there, I suppose. Instead, they found other ways to deal with the problem, and eventually managed to save all of the children, and their enslaved parents, as well. I'm guessing you have a thing with round pegs and square holes, because it's clear that all you've got is a hammer (and thus everything is a nail). Most D&D parties are a little more subtle than that. In this case, that strategy would be sentencing over seventy children, at least, to death, as the cleric wouldn't have enough time to raise them all. Never mind the reaction of the Paladin's god, cleric's god (who sent them) or their LG patron.

Archers can dominate, if all the combats are designed to play to their strengths. This does not make them broken. More than likely, they are either using house rules, prestige classes or feats that help break them, or they are just not getting faced with the right kinds of challenges.
