It IS an MMO. If people want to do the content, they can grab a group of friends and hop in. Thats what I've been doing with Anemos. I have 2 friends that absolutely refused to do it after they stepped in and killed a couple mobs by themselves.
They actually enjoy it now when we've been doing it as a group.
I also think some people go in with the mindset of "this is a grind, I hate grinds, I hate this."
