Seth is the second best early pre-promote in the series. Seth has good growths and can easily OHKO certain enemies. Sigurs does that, but BETTER! Sigurd was, imo, the first lord that was broken. If the game was just about him, he'd be neutered to Magvel and back (and Magvel for the time is an OUTREALM!), but it isn't, so they were like, "F*** it. He's only going to be in the game for less than half of it, so let's give him great bases, godly growths, and a silver sword!" Even the god Seth can't say that. Also, Seth overplays the loyal knight thing. Sigurd is a noble who is trusting and protects those he knows and loves.
