I'm maybe 3/4 through Hellfire Peninsula on an alt and hit level 63 already. Granted I had a lot of rested, but it's quick. I'm not complaining.
I totally get that desire to see the entire place though if you haven't experienced it before, and you can still do that. For the vast majority though the desire is to level to the latest expansion and cap as quickly as possible to get an alt leveled or hit 85 to play with friends, and the xp curve matches that desire.
But I say stick around if you want and check it all out if that's what you want to do.
