Last time we argued this was two years ago! And it got locked (well not locked but the poll got closed). And since then we've had tons of new kings but lets keep it to ones who we know their ruling philosophies. So yeah talk about their ruling philosophies! Is Saber at fault for Mordred's rebellion (or rather of the dynamite situation of Lance and Guinevere's love, Agravain, Mordred, and Morgan plotting to expose them, Lance killing Agravain and Gawain's brothers in the chaos after they did, and then Gawain being pissed off at Lancelot and not wanting the Artoria to forgive them when she was going to, Merlin getting sealed, and then Morgan having Mordred rebel while Seiba was fighting Lance and the Romans).
So yeah, go forth!
