The base game lures in newcomers by being the easiest one of the bunch; then the DLC kicks it up to Dark Souls 2+Ringed City difficulty and those newcomers are getting a taste of what the real game is and can’t handle it lol
I got into these games because of their difficulty. When DS1 came out, the trend was that most games would hold you hand and just give you free victories so you get your dopamine fix. The base game got a little boring because most of the bosses are just regular mobs at the end of a cave with a boss health bar. I actually like getting to the end of a small side dungeon and having a challenging fight and not just a copy of the random little dudes I’ve been one shotting as I walk to the boss room.
