Precisioned Power Attack
Your greater strength, abilities and experience in combat has given you better control over dealing damage.
Prerequisite: Base Attack of +5, Strength of 21, and Power Attack.
Benefit: From now on your power attack damage is not effected by your strength but purely on your base attack bonus. You also gain the ability to apply your power attack minus to hit, as well as bonus to damage in sets of 5; however you may still apply a full power attack if you so wish.
Normal: Normally you would be restricted to the lower of ether your strength or base attack bonus for power attack. You also could only apply your full bonus to attacks.

This solves things greatly in both concerns I have been hearing. It adds another feat to grant more power. The improved version also ensures that they have a very strong character devoted to combat so it is not out of fluff were a high dex character merely picks it up to get a great ability. It also gives us a better verity in the amount of power attack they can use giving it back its usability, but not full control to mitigate meta gaming. What do you think? I know my write up isn't the best though.
P.S. I would also like to add that this could make for a good standing point to return to the old cleave and great cleave. I miss them too, but if people still think their over powered, I don't know how the %$#% they thought great cleave was, then this feat above can be added to the list or prerequisites for cleave and great cleave.
