I don't exactly see how 'faith-based offensive power tends to be pretty powerful'. Especially when things like Dark Water exists, and the fact that they could just use other forms of defensive stats as offensive (not that faith is ENTIRELY offensive, or defensive).

Faith is a stat that not only gives you potent attacking power through the Priest offensive skills, but gives you the resource expended to do it, crit-evade and status resistance.
Yes, it can be entirely invalidated through the use of Black Bubble or Dark Water, but having two instances of complete negation in the game does not = completely balanced, just like how the existence of Red Letter or Circle Ring doesn't mean either fire or ice should never be looked at again.

Regardless, things like Sanctuary and ravaged tiles exist to counter-act field effects, making it a cat-chase-mouse scenario of who can place down their field hazards first.
