Have you even played Path of Exile? People LOVE that shit. Endgame bosses hit you for integer multiple of your HP, the only way you survive is through theorycrafting how to mitigate it (or be one of those losers who has to follow a guide)
Hell regular bosses LOVE massive damage spikes. I'm with you that it pisses me off and I since left for greener pastures (Grim Dawn)
Path of Exile doesn't have perma-death. There is a hardcore league, but dying simply drops your character to the softcore league (rather than deleting it).
This is incorrect. Dying drops your character to Standard league, which is a league that almost no one plays. It's mostly used for testing mechanics/interactions/bugs, etc. Hardcore PoE _is_ permadeath.
It’s not even just endgame bosses that can wreck your day in PoE, a few unlucky rolls and even the first boss you encounter is going to be a tough one to beat.
