Yeah I agree that as the capture quests get more expensive/elaborate the payout should increase too. Otherwise nobody will bother. For capture 400 there was a payout of over 100k - which isn't much compared to the investment, but if you have been working slowly towards that goal over months maybe then 100k in one setting is still pretty decent. Not to mention the 'capture a P horse with a pattern'
San, weird... but that's still so little, even the old system gave more, and that HEWG show one changed from under me, and i've put a ton of work training a horse and entering too many shows xD
