The way the system works now, you need to take a move action to add a +10 bonus to the leap. So someone with a higher agility bonus would need to move more to leap, seeing as his move action is worth more.

I propose "extending" the leap action into something like rate of attack- where people can spend more actions points and move 1 meter per extra action point spent to gain +10 to the attack.

So leap at +30 for example would require you to move three meters and spend three action points.

But the description in jumping doesn't say you have to move your full move distance, so there's no need for higher Ag bonus characters to have to move farther.

This of course raises it's own problem, you could just move as minimum distance for each AP spent. I think your idea fixes this too.
