The PRC is completely broken and I'd wager $100 that 95%+ of the modules do not use it. Probably more. If you bring that insanely overpowered stuff into modules you should expect to breeze through it. It's like complaining a chainsaw cuts through butter too easily.
I've yet to find a NWN module with challenging high level play that was focused on skill and execution. However, if you like extremely high gear dependencies (as in dying constantly without the right items for specific resists/immunities), being unable to do anything in many cases to enemies, incredibly important character building, and very group composition dependent content, you could check out Higher Ground.
As far as I know, it's the best option out there currently.
