Patch 3.3 has had a lot of awesome small tweaks aimed at improving the starting experience for new characters and new players, likely in preparation for Cataclysm. In addition to streamlining the first few levels, Blizzard has added something else to the latest patch notes: A new tutorial system. According to the patch notes, the tutorial windows will now be larger and contain pictures and other visual cues to better direct new players where to go, what to do, or what buttons to press on the UI. In addition, new tips have been added, and other existing tips will appear at more opportune moments.
With this, we have yet another good example of Blizzard's preparations going into Cataclysm. Despite having somewhere north of 10 million players, they aren't resting on their laurels, but are adjusting their game to invite in even more players, making it easier for them to get into the game, and ushering in a new era of the newbie (in a good way) for the expansion.
