I get the impression that the conversion of xp to gold is much smaller now (not counting the issue you described, where it was zero). WotLK level 80 dailies netted 13 gold and 23 silver. Cata dailies seem to give 10 gold and 46 silver, aside from some quests that reward 9 gold and 40 silver (the cooking/fishing quests in Org, for example). This doesn't bother me much because you wind up with a pretty big pile of gold by 85 from questing. But it does seem as if they dialed it back a bit.
