As extra information, and also to help remind those players who don’t really know what they’re doing. Maybe the game could flash a notification like:
“Your Teammates are within range of Healing Burst .”
“Your Teammates are within range of Shield Burst .”
This will help people keep track of things during chaos of fights, and will also help solve the problem of “Medics not healing, Supports not casting Shield.”
It will have to do at least until better Training Missions for the Hunter Classes arrive.
