I am fine with removing pointless fetch quest and whatnot and speeding up the overall levelling process, but the content still needs to be gated to an extent. The new stuff is simply too complicated for someone to just hop right into after grinding fates from 1-50. As it is now, people have to complete a number of dungeons and trials before they can enter HW. Remove that and you'll have a disaster to deal with.

It also makes zero sense to have access to the new jobs without completing the storyline. For one, you can't enter Ishgard until a number of events occur. Even worse, if you actually go through the DRK storyline (can't speak for the others), there's a ton of references to your accomplishments in the 2.0 storyline.
