This is a good idea, particularly for squad nights in the MA.
Right now if a member comes on late, he has to ask a series of questions: where are you/what plane/loadout/alt/target?
Imagine instead if waypoints would appear on the map, and clicking a waypoint would bring up a small box with plane, loadout, altitude.
A latecomer could just look for the green clump on the map, or simply ask what WP everyone is approaching, and immediately be able to take the right setup and navigate an intercept course.
