Can't tell if you are not serious or you're really missing something. I'm going to bite, tho. It's really hard to get a full claim on an A mark soloing and it's almost impossible to do it with an S mark. Most of the hunters are people that are gathered together via PF and hunting oriented linkshells. FCs as well. Most of them are in party. Even though I agree the hunting system is REALLY broken, since their rewards are really high, it's a huge social event. I met a lot of people doing hunting, I made a lot of new friends. In the end, this content is catering the middle guys who wants to cooperate with others. There're a lot of casual hunters, they kill a couple of marks and leave. They're NOT required to stay forever in a party. There're a lot of no-lifers as well, but they were spamming Brayflox non-stop before the huntings were added, so in the end it's the same.

Dungeons shouldn't give more rewards. They give tomes, they give money, they give gear, they give crafting materials. It's okay, nothing else is needed there, imo.
