I adore wotr, one of my all time favorite games. If it feels like a slog, really just turn down the difficulty. Tweak it to your liking. I keep the difficulty really low and sometimes just turn it right to the bottom when I don't feel like any challenge. You have a lot of options to customise the difficulty, my biggest advice is to use them.
This is my take on the game too. I often find myself turning the difficulty down all the way when the combat becomes a chore, especially where a lot of pre-buffing of my party becomes a necessity that I don't want to do. And for me, the story of WotR is awesome (note that I say story and not necessarily the quality of the writing). I love playing the goodly hero laying down the hurt on evil everywhere, so playing Angel Oracle has been stupendous!
