Oops, I mistook that for Skien's Madness lol I don't think even with support, heavy spell will be a viable combo outside of sets. I'm not seeing how Ensa's Faith really pushes WFA. If anything, I'd toss it on EWF builds more often (though it works on both). It's not like it really needs a Def req, just felt a little strange. Normally I am the first person to agree with this, but even with the defensive benefit, I do still think it doesn't have the power to make up for the health penalty.
