No, seriously, this Jeigan is the worst. Francine kills everything, so I can't use her to soften anything up. She's basically dead weight. At least until enemies stop having so little speed they get doubled by a unit with 8.
That... never really worked for me. Even after he got the Tyrfing, I had to make him canto in and out because he got murdered if too many enemies attacked him at once. Sure, that sounds reasonable, but I'd say it kinda knocks him out of the Seth competition.
Okay, then maybe it was turn 2. I remember with absolute certainty he almost died on the first pack of enemies he fought in the game.
