Back to the grindstone

My playtime is 'probably' going to be much more limited over the next few days, simply because of real life commitments, but I'll no doubt manage to get a few hours in here and there.
But will it make any difference?

I reached level 71, with myHunter, on the day of release. And I was quite pleased with the levelling speed. However, 71-72 seemed to take me forever, probably almost twice what it took me to get from 70-71. Yet I'm now already a third of the way to 73.
I'm not complaining, and I think I've sussed what the problem was.

I was trying to complete all the quests in one area before moving on to the next. So I think I've finished all but a small handful of quests in the Howling Fjords. But the travelling time, and all the to'ing and fro'ing cost me alot of time.

I've now moved on to Dragonblight, and I'm picking up quests in batches again, and my XP bar is filling up nicely. In future, I think I'll skip to the next area as soon as the quests start to thin out.
Any quests that I miss out on I can either come back to do later or will catch them next time, probably when I level my DeathKnight.

I've noticed though, that most of my guildies are still no higher than level 71. (The vast majority are 'social' players and don't spend massive amounts of time online though).

So what do you think?
Is the levelling speed about right?
