I'd like to get rid of the Piety skill - or at least the alignment tied to it - too.
Because of the following implication:
For me, piety is the strength of connection to "the gods" or how strong your believe is.
And in game terms it means: The more you believe, the more evil actions you are "allowed" to do. Thats what I see as wrong with this system.
In my view, the deeper your believes are, the better you would behave.
If, of course, the system is meant to mimic fanatics, who are not distracted from their goals by other people being in the way, then is has its place.
Since it is with the crafting skills, it means that those who wan't to be more skilled crafters, are not as good as those investing in piety.
And those that want to mainly fight - can just invest in the skill to have less penalty for killing, because they have less need for crafting anyway.
Thats wired the wrong way in my eyes.
