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

[Dyvid]

Do people that would call themselves casual think this game is too hard (if you think about it, it is basically the thread title).

No, I think it's balanced just right. In the typical MMO sense of the word, hardcore were player that could devote anywhere from 4 to 20 hours a day playing the game where as casuals were between 30mins to 4 hours. Challenge in elder gaming was based on time to complete, not actually difficulty (maybe this game design was also influenced by internet connection in the late 90's, early 00's). Fast forward to today and I think the term casual best suits content that can be finished in a random group generator (Duty Finder) where as hardcore requires more coordination and communication as well as experience with the content.
