Before the patch launches you might want to grind your gold out to an 'even' numer like 100 or 50. As far as I know the tavern pass only gives you rounded amounts of gold(100,150,300 etc.). So if you don't do this you will be stuck with an unsatisfying amount of gold forever, unless you play arena.
Something not everyone will care about, but worth noting at least.
XP values displayed in Quests above are not final. Please note that when the Progression revamp goes live, all Quests (with the exception of Starter, Returning Player, and Duels Legendary Quests) will reset, so be sure to complete any old Quest you have in your log by November 11!
You'll get XP for wins instead, which will pretty much directly result in getting gold. I expect it'll all be calibrated so that you'll end up grinding gold at about the same rate by playing. Definitely expect the focus to move towards playing rather than just winning, so if you were playing to optimise wins/hour you might suffer
