Anti mix-packing mechanic
Sometimes large sized Carnivore / Herbivore mixed packs using discord to meet up, at hot spots of the map for trolling purposes and kill all the players who are questing / growing. This is a problem because toxicity and resentment make for a over all more toxic community in pvp games. My solution is adding a nasty Debuff to mixed packs that attack the same targets, this will be tricky to balance but I think this would make people happier about spending time on the game, and clean up global chat passively. You could even make it stack on hit.
