Many of us know potential new players who are discouraged by the time sink of A Realm Reborn (@Square-Enix - these people are lost money!).
Presumably we can assume computing requirements will be raised on the onset of 5.0.
So for the whole of 2.0-2.55, we can preload multiple ARR areas.
When the player is done interacting with one NPC while doing the 2.0-2.55 main scenario quests, prompt them to teleport directly to the next point they need to go to at no charge. If this "point" is an area with an animal to be killed, nerf the animal and reduce the number of killings to 1.
Should the player decline any MSQ teleport, keep the ARR-MSQ teleport available by clicking the MSQ indicator that now ordinarily shows up in the top left of the screen.
When 5.0 is released, perhaps both A Realm Reborn and Heavensward should be expedited in some manner.
It's already not easy to watch new FC members plod through 400 quests to get to Stormblood, and I'm already noticing we are getting more "transfers" from people who are already 70 than true new adventurers.
