I'd say that most of the characters, especially bruisers/Fighters/Tanks like Garen, Xin, Olaf, J4, GP, Lee, Shen, Riven, etc,etc. would have Fighting as one of their primary attributes. However, their secondary attributes might differ a bit, eg Nasus might have ground as a secondary attribute, Garen might be Normal,etc

Also, I'd say Diana is more of a Dark/Fairy than Fairy/Steel simply because while her crescent sword may be steel or whatever, her moves,mood, and overall theme are about night and the moon which suggests Dark as a secondary attribute...
