Quite simply- the ability to track revives done by faction members, much the same as attacking is tracked within a faction.
Clarifying edit: Not necessarily have'revives on a separate 'tab'. I'm looking to have the revive information added to the API for factions like attacks, donations, and armory events are. Doing this would enable the ability to query this information in a given time frame to see how the faction members did. Much like a chain report is created with the attack news via tornstats.
