Think of your OCs like actually RP characters. One is a Warrior, one is a Mage, one is an Assassin, another an Archer.
What you need is individual experience on all of them. You'll notice that among my Ocs Wyst uses the spear a lot and then Gwenrhian does the same thing, Furījia does the same thing. Meluse attacks with flexibility and glancing blows and Sagisō does the same thing. In fact, most if not all of my characters are quick female who use a flexible battle style with pole-arms as a weapon of choice.
What you need is repeated experience with your character to see how people react to them.
Experience with the fighting-style is what you need.
