Would I rather kill an enemy ( or more than one usually) and/or inflict huge amounts of damage on one, or debuff their willpower and bodybuilding so my mage can put a temporary status effect on them which may not affect the fight much at all?
I tried to point you out The light skill once we have disputed the warrior skill usefulness, but your narrow type of vision is known :-] However The Light reduces both saving throws at once for 3 AP without a chance of resist. Therefore its very handy before apply any skill like knock, cripple, stun, charm ... which are re-rolled to saving throw every turn. Frankly speaking, you can make sure that target you are knocking down dont stand up to early.
Felix your advices sounds loud and confident like from expert, but ... .
