FF games are traditionally story driven. Story driven content tends to be locked on rails.

What do you suppose they do? WoW style rep grinds? WoD(latest expansion) released a load of old school rep grinds and open world content(latter, specifically this latest patch). You know what the general consensus is?

"Wtf Blizzard, this shit sucks!"

And instanced dungeons don't separate friends. Only certain roulettes.

Duty quests being forced solo is annoying however. ESO did that.... Rage.
