Hi, I would like to suggest a feature to identify the party members within range for spells or just within a close distance. An icon, a different color, or transparency can be used as identifier.

How will this help?
In PVP:
The proximity identifier will let the player know who is within range for party spells like Focalization, BRD spells, AoE healing, etc. There are also cases when the party has to split up and when a member needs healing or support, there is no way of determining if he/she is within range or on the other side of the map other than looking at the actual map.

In PvE:
A bit of the same reason for PvP when it comes to party spells especially in duties when players have to split up. This can also be beneficial for single target spells such as resurrection, aetherial manipulation, Eye for an Eye, etc.
