Given that diversity is an important part of alliance war scoring, it would be great if there was an in game way to facilitate picking diverse defenders. Some ideas for implementing include:
- a portrait icon similar to the existing indicators for AQ, AW, and active in quest
- grey out defenders already chosen
- a filter option to hide defenders already chosen
- a warning message that pops up when you've chosen duplicate defenders
Incorporating one or more of the above suggestions would remove a barrier to AW success for alliances that aren't using a bunch of 3rd party communication tools and roster utilities, and it's in line with some of the quality of life improvements like adding prestige visibility and assigned battlegroups.
