It's your character, so fair enough, from what I know of First Nation People's they tended to favour guerilla tactics where being physically robust in a pushing and shoving sort of way (which most medieval battles tended to come down to on the front line) was not a major concern, nor something they trained for.

Common misconception. 

If battle turned into shoving matches, the people in the first and second row would suffocate to death and cause all kinds of cohesive failure for the unit as a whole. Imagine 12 or more people pushing you from the back while being waged up against a dozen bodies in front of you. Total chaos. 

Melees are actually something generals absolutely try to avoid. You'd have an insane amount of casualties and little tactical gain.
