Hot take: tag friction is a feature. Fighting over a mob is how strangers end up in a party, and that party is how they end up in a guild. Make everything shared and soloable and nobody ever has to say hi.
Blizzard already said no to shared tagging. Players are still arguing about it.
Aggrend wrote on September 20 that Forever must "hold the line" on first-hit tags. Shared-credit fans want crowded quests to stop feeling like a mosh pit. First-hit fans say that friction is what makes strangers invite each other. A Forever beta thread on that fight now sits at 331 posts and 512 likes.
We are with the hold. Forever sells a social world. Shared tagging deletes the reason to talk.
Shared credit on every tap, or first hit owns the kill?
