Removal of Piety and Related Rules Changes

I have concerns with Wield Faith and Malediction not have a number associated with them now. I think their needs to be a distinction in being able to turn a lesser skeleton vs. being able to turn a regular skeleton and a difference needed to be able to strip a 5th level priest of his powers with malediction and a 20th level cleric. However I see the problem if you use level to drive this because I could be a 20th level warrior pick up priest and wield faith better than the 10th level priest even though he has more "faith skills". Since using level is not a viable solution I think Wield Faith and Malediction must be made into Tag skills that can be defended against with whatever defenses you deem defends you against the greater versions.

Those concerns are already addressed.  More powerful undead won't be able to be turned by Wield Faith - they will require Greater Wield Faith.  As for Malediction:

To use this skill, the character must affix her holy symbol to the opponent, who must be rendered immobile by some means. She is unable to cast prayers or utilize any divine abilities for as long as the character’s holy symbol remains affixed.

So if sad 20th level target is going to sit there while his 5th level opponent asks him politely to hold still while he affixes this holy symbol to him, he deserves what he gets.  Malediction is not so much as combat-oriented shutdown as a "We've got him down, now let's cut him off while we can so he can't escape" thing.  You still need to take him down first... and remember that most things like Imprison, etc. won't let you target the captive, so you can't use those as the setup.  And nothing is stopping the target from taking the holy symbol off unless they are physically secured first.
