I have now updated Swarm to take advantage of the new map waypoint functionality that was added in 9.1
Now when you target a waypoint is added to the map and the link sent to chat.
This allows players to click and a waypoint is added to their map, so no more trying to hunt using coordinates.
Maps that cannot have waypoints, such as garrisons, will print a cannot add waypoints message.
This new feature only works in retail as this new functionality is not available in Classic and BC. I will continue to monitor both Classic and BC to see if Blizz adds this functionality in the future.
