This idea/suggestion is Open. You can respond to ask questions or discuss the idea and either vote it up or down if you believe it should or should not be implemented, respectively. Popular suggestions and ideas will be considered by the development team to become reality in-game.
Proposal
Implement a system to allow group leaders to form multi-group groups. Purely a UI change to show other group's nameplates/health bars. In no way should this expand group buffs/benefits to additional group's members or increase the intended group size for specific content (ie Heroics)
Justification
Primarily PvP/GCW related but any open world content such as live events would benefit from allowing these multi-groups

Direct benefits
  • Group leaders would be able to see all group's members reducing downtime during formation and when making adjustments
  • More opportunity for coordinated movement due to being able to see direction indicators and range
  • Healers would be able to more readily locate and heal those not in their group ensuring those that couldn't fit in the main group(s) are not left behind
Motivation
There is a variety of content in the game that expects multiple groups to work together in a coordinated effort. Not having a multi-group UI adds unnecessary downtime both before and during events and unnecessarily hinders coordination during the event
Forming and maintaining multiple groups is a headache
Coordinating multiple groups during a fight is a headache
Healing people not in your group during a large fight is a headache
Less headaches more fighting
 
Raid groups provide buffs to all members, this idea would not do that. I intentionally did not use the term raid group in the write up so that it would not be perceived as wanting a WoW-esque raid group system
 
I'll admit I shy away from massive content moments that have multiple groups. At least trying to coordinate with them. Coordination is "Part" of the reason but not all.
Be nice to be able to call out for help or know who to help without necessarily using a discord call.
 
If I could resize the group(s) window's this would be amazingly handy as a healer, this laptop's resolution is mediocre so I wouldn't be able to fit more than my own group, but for those of you on desktops with nice large monitors I can imagine this being very beneficial. Upvote
