Patch 5.3 has arrived, and there are a truly staggering number of changes to the game, many of them with significant effects to gameplay. You can check out Blizzard's complete patch notes on their blog, but for the sake of brevity, WoW Insider has compiled a list of the top five changes that are most likely to be of the biggest interest to the average player. If you haven't been paying much attention, this is the stuff you probably really want to know!
1. The experience required to go from level 85 to 90 has been reduced by 33%
Mists of Pandaria has been called very alt-unfriendly, and while this particular change won't entirely fix that, it does help. Along with the changes to reputation factions -- the Shado Pan and August Celestials dailies are no longer hidden behind the gate of "Revered" with the Golden Lotus -- this will make it easier to get your army of alts up to speed to hop into max-level content.
