I think that developers should rebalance rewards for quests or, at least, to make some rewards more appropriate to the in-game situation. For example, the reward for helping the dude from Ivarstead to get supplies to Greybeards is 1000 gold. Are you serious? For 1000 gold that man should get that bag up there 10 times himself. Where did he get all that money? It's against all common sense. 100 gold would be pretty fair amount for that job. And this is just one example of many.

Pretty sure misc quest gold is levelled - probably to entice people to actually do the quests.
