Yes, get to 70 as fast as possible.

I don't even see the point in saving quests *now* given all the daily quests. Grinding 60 -> 70 takes you longer to level... a lot longer. Is it really that much faster to earn gold through saving quests that you have a net decrease in time /played combining the grind time to 70 and doing all the easy quests for 5000G, versus blowing through the quests getting to 70 and then grinding cash through dailies? I seriously doubt it.

Grind to 70, do skipped quests for gold = X days played total
Quest to 70, grind dailies for gold = Y days played total

In my opinion, Y > X by a good margin. And definitely if you consider that the sooner you get to 70 the sooner you can start gearing up, it's a no brainer to me.
