So he performed pretty well in combat though? And didn't die in all of that? That's a pretty good sign. Hopefully he would generally avoid his own death, but rout when the army reaches 75% losses.

He may still be missing that one thing that makes him an integral and compelling part of your strategy. As it is, he's more of just a really nice hero (oh, ironic) than an actual pretender.

A #onebattlespell may be a good option. Not sure what you would use that would be thematic, useful, and balanced. Since he's meant to be magicless, Antimagic could be an interesting buff for him to apply. And that's definitely one that doesn't do a lot early on, but later in the game would make him an incredible tool for your armies (at least in MP, not quite as much against the AI).
