How do people calling themselves casual feel about the difficulty level?

[Noahlimits]

Two hours a night is kinda hardcore wouldn't you think?

Hardcore, casual etc are all subjective. Is someone who plays 4 hours a day yet only does basic content (no hard content) hardcore simply because (s)he plays a lot? Or is the person who plays for 2 hours on Monday clearing all EX's and coil for the week hardcore?

That's one of the reasons I never liked that debate since it's all up to the perspective of the person viewing it.
