He said all CANON characters. Sonia was retconned, and isn't canon anymore.
I also thank whoever posted the picture of Sophitia, the sheer size of those things make me laugh everytime.
It's a fact that most men are more able to become fit as a warrior than women. However, if the women is say, more determined or trains more, she can become better than him. It's just a question of potential and who reaches it. The Amazons for example, in their ideal society taught them selves and trained as warriors. It was easy to become a warrior and they constantly became stronger, making them very good warriors.
If you put them against untrained warriors, they would rape the hell out of them. It's like putting a monkey against a human, and you train the monkey how to drive a golf cart, and let it learn the track, but leave the human totally untrained as to driving. The monkey would win despite it have a disadvantage in something like that. *is not comparing women to monkeys*
And like someone had said previously, think of the time periods most games are in. A female training as a warrior was rare, and so it would be a lot easier to train as a practicioner of magic.
