Eden Ring is for that specific group of masochists.
I'm mildly shocked someone into XI wouldn't be into Eden Ring. It's constant ball punching, you should love that aspect. Finding the most broken thing and spamming the *** out of it. Min/maxing or wasting your time is peak XI.
those are completely different type of masochists. FFXI, like any other MMO is for casuals. the "difficulty" comes in form of gear requirements, dependency on others and bottlenecking like limited drops for a large group or beeing locked out of content for a while after very few attempts. they are only hardcore in the time wasting department.
the dark souls games give you as many attempts as you want but ask for quick reflexes, good timing and the willingness to learn while you repeatedly smash your head against a brick wall till it eventually breaks.
you could run thru dark souls pretty much naked with a broken sword and if you're good enough you'd still be able to beat the most difficult enemy. something that would never happen in FFXI with skill alone.
