Aeine, a promoted Soren makes a ton of other contributions. With him and 2 paladins a 3 turn of 17-1 is possible. He can ORKO Shisharam with siege tomes, And we need a siege tome user for a bunch of senarios anyway.
Uh... a 2-turn of 17-1 is possible with one Paladin.
By 20 you can easily get Soren to promote anyway... do you not realize how tight bexp is?
