I'm pretty sure they also increased the number of resources recieved from hunting the rest of the monsters above level 1 to balance risk/reward. I don't remember the exact numbers.
But it might break the game to increase rewards without the coming watcher buff included aswell.
Yeah, I also remember seen/read it somewhere (maybe on TwitchGameNight?). If someone can recall, please let us know. I'll update the document accordingly. Thanks!
