I noticed last patch there was an attempt to make some dungeons more difficult. I have a suggestion on how to do that easily and remove a bit of awkwardness from the game:
Make Waypoints in dungeons have increasing timers upon use.
For example, if the WP is used once, then give a 30 second timer before it can be used again. If it is used again, a 1 minute 30 second timer. Then, a 3 minute 30 second timer, etc.
This timer could reset upon a complete party wipe or the individual being alive and not having used a WP in the last 5 minutes.
This would make encounters far more difficult as it is currently a fad to WP-rush hard bosses that would normally wipe the group.
