depends on your approach imo. there's a lot of ways to make it easier similar to how ER has big shields, magic, summons and ashes among a lot of builds and other options which crack the game in half
personally i went for an all points in Atk build(no softcap like in Souls as far as ive seen), with no real use of shell spells(the magic equivalent as you'd imagine) or shelling(shielding), just because i enjoy having these be as challenging and cutthroat as i can
and it's been a really goddamn fun challenge. enemies just start hitting like trucks as the game progresses but you also get drastically stronger with so many new additions to your moveset like air dodge, shell-parrying and dodge-parrying into riposte, topple punish and it's just so so much a fantastic time.
also some of these bosses are just such an awesome time to fight, the movesets are so varied without feeling overly oppressive. once you learn parry windows on some of the big guns you feel like a god toppling them like nothing
i'd highly recommend this 'path of most resistance' for someone who craves a good souls challenge like i do(as someone whose last Souls playthrough was a Soul Level 1 run of Dark Souls 1 lol)
