Theres a lot more new ones out there. Some of my favorites:
•To ensure Orgrimmar and Stormwind are the premiere cities for Cataclysm, NPC’s have been removed from all other cities.
•Female worgen have been cured of their curse and now have only a human form.
•Ever a player favorite, the level-80 10- and 25-player raid of Icecrown Citadel is being reintroduced as a level-85 Heroic 5-player dungeon.
•Ever a player favorite, the level-85 10- and 25-player raid of The Bastion of Twilight is being reintroduced as a level-85 Heroic 5-player dungeon.
•Ever a player favorite, the level-85 10- and 25-player raid of Firelands is being reintroduced as a level-85 Heroic 5-player dungeon.
•Ever a player favorite, the level-85 Heroic 5-player dungeon of Deadmines is being reintroduced as a level-85 Heroic 5-player dungeon.
•In order to make the Cataclysm expansion appeal to all players’ sense of nostalgia, shaman, druids and paladins may now only queue as healers when using the Dungeon Finder.
((I actually remember my raid leader refusing to give a dps cloak to a paladin in ZG because "paladins only should heal"))
•Female warlocks are now correctly called witches.
•Rouges equipping helms that resemble eye patches now suffer a 2% hit penalty from lack of depth perception.
•Some paladin abilities did not contain the words Sanctity, Divine, or Justice. This has been corrected.
•Hunters now earn Valor Points when they are effectively Vote Kicked from a Dungeon Finder group.
•Druid forms are now considered vehicles, allowing one player to ride on the druid’s back while in any form, even their humanoid form.
•Due to player feedback regarding night elf, blood elf, and worgen “flippy” jumps, player characters can no longer jump.
And finally my favorite:
•The mouse can now no longer be used to turn player characters. In many cases, this gave certain players a slight advantage over those that used their keys to turn.
