The reward output of charms and stones, is extremely low. The charm output now is like 3 per 10 wins, which is at best a weak surprise. Usually you get nothing. There is very little incentive to win a pet pvp battle. Rewards like the Stunted Direhorn at 250, and the Family Brawler Tabard, get people motivated to queue up for pet pvp, but it’s not enough. The Queue is dead. Like 1 queue pop per 2 hours. Actually maybe less than that. It’s because no one cares about the rewards.
I suggest 2 charms per win. That would not break the charm economy. If people actually started participating in the pet pvp queue, in order to farm a measly amount of charms, the queue would actually be functional, which i think is really the bare minimum goal. Why not reward players that brave the scary and toxic pet pvp queue with something? You gotta give at least 1 charm per win, and then sometimes it should be like, 5 charms, randomly. Like a slot machine. Right now the most valuable thing you get from pet pvp wins is the XP.
