Most people speaking to Demon's Souls' difficulty are probably thinking about their first experience with it, when they're not going to have a Sharp Falchion + 3 at their disposal (especially not that early on). When I got to Flamelurker on my first playthrough when the game came out, the trek to the boss + my lack of skill with the game and poor understanding of the mechanics made him seem insurmountable.
Brad is in a very different situation, years post-release with all the knowledge he's absorbed and with someone who's beaten the game and a chat room there to help him out. He chose a class he heard was easier, and is using a weapon that he was advised to pick up and use (and advised how to get the best out of it through upgrades and levelling). There's absolutely nothing wrong with him playing the game this way, but he shouldn't be puzzled about why he may be having an easier time of it in some spots.
