FFXIV dungeons are a little bit too linear?

Casual players will complain game is too hard and rage quit. Also PS3 limitations.

I think you're a little backwards here. The casuals are the ones who would like this the most. They wouldn't mind stopping to smell the flowers and appreciate possibly labyrinthine design. It's the "hardcore" crowd that would hate it and demand people take the fastest route.
