You're right. I used the wrong word when describing his fighting. The direction I was trying to take that was basically to say that his reflexes aren't particularly fast and he knows that, so he tries to take advantage of opponents' own openings rather than making his own. Similarly with the strategy, I was trying to convey that that was what he cared the most about, not to say that he was a genius with regards to it.
He's older than Kane, and more set in his ways. He doesn't care about changing the kingdom, he cares about doing right by the people under him. Kane might have talent and training, but Royce has experience. In demeanor and action, he's more reminiscent of a seasoned sergeant than a noble knight. In court and among the royalty, he's awkward not because of an idealistic desire to fix the place, but because nothing about him fits with the culture of the upper crust of society. He's scarred, he's huge, he's angry looking, he's got a limp and he's missing fingers. His physique wouldn't be similar to Kane's simply because they trained in the same place more than fifteen years ago, and his skills and fighting style wouldn't be the same because that's never the case.
Look, I'm not trying to start an argument. I'm just saying that I can emphasize the differences or make a different character. I'd prefer to keep my character, as I think writing him could be quite a bit of fun and the way I'm picturing him is quite a bit different from how I picture what I read of Kane. If that's a non-starter, I'll just get the creative juices flowing some other time and make someone different. Probably that scheming nobleman I was talking about.
EDIT: Edited to elaborate.
