Waypoint Exploit

When adventuring, it is possible to skip large areas as following (using royal crypts as an example)

(solo)
Enter the royal crypts
Recall to town
Take waypoint to royal crypts

(Party)
Have one team member reach the crypts while you are in town
Take waypoint to royal crypts

This allows you to bypass most of that level. Could potentially be a significant exploit in later parts of the game.
