Elden Ring Nightreign could be the Fortnite of Soulslikes, but probably not for the reason you think
As anyone who's killed their fair share of Tree Sentinels and Erdtree Burial Watchdogs will attest to, Elden Ring is no stranger to recycled bosses. These reused battles tend to take place in optional areas of the game, and if you're lucky, make slight tweaks to the original fight (the classic being: oh great, now there's two of them).
