Bloodstone and power critical feat

Now that I have acquired a bloodstone, is it a good idea to swap out the power critical feat for something else?

My toon is a 11 paladin 2 rogue 1 fighter, and has power critical as my fighter's bonus skill. Other feats of note are: toughness, power attack, weapon focus: slashing, and improved critical: slashing.

Thanks for any advice.

Power Crital sucks. It doesnt add bonus damage like seeker, and there are better feats to select out there. Drop the feat.

If you have a high enough str you may look into stunning blow or CE+Improved Trip (dropping toughness)
