The Rise and Fall of the Lich King: Contest (Source)
The cold winds of the north are not stayed by armor or weaponry, but slip through the links in the armor and bite at the flesh beneath. The Scourge answers to but one king and he is a terrifying foe. Enter the heroes of the Horde and the Alliance to match steel with steel and face down this walking terror and his minions in the cold steppes of Northrend.
We're looking for your best screenshot of your own effort to put a damper on the machinations of the Lich King and the Scourge in Northrend; you could win a Rise of the Lich King Stein.

Mobs and their unpredictable movement since 3.3 (Source)
There is a known bug that was introduced in 3.3 that can cause tanked mobs to move around in unpredictable and frustrating ways. A fix is incoming.
Ephermal Snowflake (Source)
The Ephemeral Snowflake now has a tiny internal cooldown to keep it from being overpowered on spells such as Vampiric Embrance (when dotting multiple targets) and Wild Growth. It will still return mana as expected in most cases.
Has the game gotten too easy? (Source)
I can come up with many examples, and ALL of them are positive changes from one perspective or another - my concern are these changes as a whole, as these changes are continually implemented the direction of the game is getting even easier then it already was.
You're welcome to your opinion of course. We don't think the game has gotten too easy. Very few players have been able to defeat say heroic Anub'arak or Yogg-Saron in his hardest mode before that. High level Arena remains as challenging as ever.
We made some changes to make the game more accessible, which I don't think is at all a bad idea. It's awesome that WoW has as much depth as it does, but we don't believe complexity, and particularly not confusing complexity, go hand in hand with depth. It's a social game, definitely, but social doesn't have to mean that it requires an experienced friend to teach you how some unintuitive mechanics work.
As a player I can understand how you might have a sense of accomplishment for being able to overcome a very hostile world or leveling environment. It's fun to be challenged and overcome those challenges. But you can also think about how it benefits you to have the audience for this game grow as large as it has. We are able to release relatively expensive content (3.3 was a gigantic patch by almost any measure) because WoW has been so successful. We are now talking about our third full expansion and beyond because it's clear that WoW has enough players to endure for awhile. So while it definitely benefits us to attract and retain new players, it ultimately benefits you too.
There are MMOs out there who cater to a much harder core audience and there are ways to make such a business model work. WoW just went in a different direction. We're big and ambitious and we want to keep the game going and growing for as long as we can.

Shadow Word: Pain needs to be hotfixed as well (Source)
We think Shadow Priest dps is in a good place without SW:P benefiting from haste based on the data we have seen so far.
Warlock
Rolling Corruption bug and Affliction DPS in 3.3 (Source)
If you thought the Affliction Corruption rolling was fine, you probably weren't playing it correctly.
I'll admit it required some level of sophistication to pull off. But we don't think it's fair to let some players do ridiculously high damage just because the average player can't do it.
