Was Ruben boss fight nerfed ?

I just finished my Dani run on ps5 today ( lv 25 at time of fight ) and with my preferred load out I mostly used a electric machine pistol and within about 2 clips the fight was over

Didn’t have any issues with spawning zombies

Similar with specimen Noah too those fights I always was worried but it felt like a joke compared to when I did an Amy run on the series x
