I for one am for this idea. We are all well aware that leveling sucks and is a time sink but that is the classic experience. To level fast by a cheese or bending the rules hurts the community as a whole. You think leveling is slow and horrible, try leveling when you are in your 20s, 30s, 40s and all the zones are dead. Good luck getting a group together for a rare quest or dungeon quests.
On a side note I am curious of the opinion one might have on dungeon boosting vs the paid boost blizzard is offering? IMO blizzard is doing you a fav and saving you some gold and possibly IRL money.
But hey #nochanges if it interferes with my gold selling opportunities.
