Obviously people desperately need this. There are too many people out there who can not figure out things on their own (or feel they should not need to). Nor can they read the forums/guides (or feel they should not need to). Therefore if we wish to welcome these types of people we need 'rails' or every single support mechanism possible to make the experience as passive as possible (up to the point of: hit button to make big explosion).

Or... FFXIV targets a different segment of the market: Those who can figure out things on their own and do not need constant guidance.
