I disagree with wilpower being there for 2 reasons.
1. Will is already a VERY important stat and is considered in max fp calculation.
You *could* say it's your force of will to go on, but that's probably stretching it. End and con are your physical limits and exist for a reason.
2. Force of will could mean anything. People with high wil could get a bonus to spellcasting because they try harder, to weapon skill because they are more determined...etc
If we were going to change it I would lean towards a con/end combo myself.
