For most soloing, I use a build that's mostly LtC and then goes into LoM just far enough to get Noble Mark. I sometimes switch over to a full LoM tank build when I need to be a "one Captain fellowship" and take on something really tough. I haven't bothered customising that into a true LoM solo build, but it'd probably be a good investment of my time -- LoM's threat mechanics are kind of handy in the Epic Battles, even when you go in alone.
