First idea can only be done with the elimination of being able to see enemy tags. Unless the player mouses over any enemy. Then the enemies tag is visible.
Suggestion
*Add reconnaissance to WvW
*players can choose play a reconnaissance role. Buy using unique equipment and skills.
*Reconnaissance players can call out enemy positions.
*Reconnaissance players can use drones
Think of this idea as GW meats Navy Seals. But with weapons and equipment that fit the GW2 theme.
