Yeah in Dark Souls after a certain point, the bosses were pretty easy. I think the hardest boss was the Capra Demon, and everything before was pretty damn hard, but beyond that everything was pretty simple. Maybe I was overleved/overgeared or something. Max stamina + havel's set was pretty OP.
Dark Souls' final boss was at a perfect level of difficulty, though. Took several tries to figure out all his attacks, and even after that, you had to have good reactions to beat him.
