I think one way to re-balance the campaign exp would be to award exp based on enemy level rather than just number of enemies. So instead of getting 1 exp for defeating a single level 6 enemy you'd get 6 exp, 3 level 4 enemies would give 12 exp, etc. I remember seeing people frustrated that even though certain battles were more difficult when they reached them in the campaign, they still only got 1 exp for the battle, slowing down progress.

I think this would help with potential "wolf saturation" too because part of the problem is that it doesn't feel worth it to level wolves. It takes a lot of time and stamina, and it can feel like a slog because of how little exp you get in the campaign.

Support. I'm not sure if they plan on fixing up the 2nd chapter with better exp, but I think this would certainly help with leveling and releasing of wolves.

At the very least, I'd love this for the boss fights.

For the meager rewards it gives, leveling and releasing should be far easier than it currently is, so I'd support a change that went even further than this as well. Releasing is ultimately for the health of the game, so driving it with frustration instead of encouraging a healthy churn of wolves is an odd design decision. It doesn't even necessarily call for better rewards (though they are just miserly as it is, so improvements would be welcomed regardless) just a better, streamlined experience leveling the silly things.

Absolute massive support! It makes no sense that defeating 3 lv 14 enemies rewards the same xp as 3 lv 7 enemies.
