So I remember Anet discussing how they didn’t like games where players would compete for kills, and instead they divised a system that shared loot.
So why doesn’t this apply to guild bounties? Sure, if 2 guilds work together, they both get credit…but if nobody mentions in the chat that they’re fighting said boss, the bounty will reset. Thus forcing the second guild to look all over the map for a second time.
If you can read this then it is proof that ArenaNet’s moderators just, kind and fair.
