Yeah, the word "war" hints at competition but it literally means violent conflict. I know of no association between "war" and a metaphor for self improvement. You should make that clearer if that is what you're going for. However, with "war", "kata" and "enlist" it seems pretty obvious you were going for a martial arts/warrior theme. It's kind of patronising to pretend that theme isn't there just because someone doesn't like it.
