Do you guys think jump checks should scale exponentially instead of linearly? so say a dc 10 would be 10 feet sure but a dc 20 for one is 20 feet for the other it would be more like 80 feet. (that might be to fast) I guess the ideal is that the effect of hitting higher dc's would be greater.
Hmm or maybe even better that the Proficiency would make all skill checks effect more substantial even without skill feats.
I also think some skill feats could be combined and have unlockable parts that are unlocked by higher prof.
