I played through up to early monolith levels in the hardcore mode as my first experience of the Last Epoch, and I notices a few things, but before anything, I wanted to point out that the so called hardcore mode has no place in current ARPG market.
Most of the famous current content creators of Path of Exile I follow on Twitch (which is more than a dosen) was once a hardcore player as far as I know, also I had literally tons of hardcore friends in my frend list ages ago, and now I have not a single friend who plays hardcore mode anymore since years.
This is my opinion that many people actually love to play hardcore mode if the game could offer a good environment for the mode, especially in early development stage of the game release, and there is enough market size to pay ‘a little bit’ of attention to it for developers to cater those people.
Let me reiterate this. Crrently there is not a single ARPG online game in the market that pays due attention to Hardcore mode. Maybe Last Epoch can be the one if the developers so desire, even though current state of hardcore mode in Last Epoch is not at all optimal even compared to the open beta back then of Path of Exile, since some classes and unique items are way too strong and other classes are way to weak for HC from my experience.
(if anyone know past history of conversation on this topic with devs, Im interested in knowing it)
