Players on the beta have noticed the levelling speed on the beta between the levels of 60 and 70 seems to have been increased. The total amount of XP needed per level is lower.
Tigole answered the queries about whether this will be permanent, on the official forums:
[blue=http://forums.worldofwarcraft.com/thread.html?topicId=8202385165&postId=82016278245&sid=2000#12]Yes, we’re planning on speeding up leveling in the 60-70 range. Keep the feedback coming. We are still adjusting it. Let us know what levels you are in what areas in this bracket. [/blue]







Dumb, folks will have barely broken out of Nagrand, let alone hit Blade’s Edge, Netherstorm or Shadowmoon if they up the leveling speed between 60-70. The only way I’d find this acceptable is if Blizz created an option to display all available quests, even if low-level, that way I could go back and complete some unfinished business. An increase in leveling will do nothing more than force folks such as myself to skip content, when our desire is to explore as much as possible before outleveling a zone.
