Update - Added today's news to the post. Blue posters have been surprisingly calm yesterday, that's not the first time but it could mean great things for today.

Notes about the class changes list
A longer explanation might get the attention of most of the users. The list posted yesterday IS NOT from the patch notes, it's more than likely a leak from an internal mail/meeting discussing potential changes for classes. 90% of them probably won't be in the initial release of the 2.4 Patch on PTRs and even if they're added later, keep in mind that you'll be playing on a TEST server used to ... test changes and see how it works with enough people to gather an accurate feedback.


Spell haste and Global Cooldown
In 2.4, Spell haste will let you decrease your global cooldown, Nethaera explains how efficient it will be.


Raid UI changes in 2.4
Another feature has been added to the raid UI in 2.4


Blizzcast Episode 2
The Episode 2 of the Blizzcast is currently in post-production and will probably be released in the the upcoming weeks. Bornakk reminds people that you won't necessarily see tons of new things here.

If you missed the first Episode you can download it here or just check its page on the official site for a transcript/stream.


2.4 Potential class changes
Read this first

• It's unconfirmed and potentially fake (50% chance I'd say)
• Most of these changes won't be in the initial release of the 2.4 Patch on PTR, it's more a todo-list for classes changes than a full list of changes at the release.
• According to the source, they're a list of changes that Blizzard will like to experiment on the PTRs. You won't see them in patch notes until Blizzard decides or not to test them on a PTR build. That's why they're called TEST servers
  
  

The "Blue posters are always right" minute

This could perfectly be a fake, seriously, if you didn't read this before going through the changes you'll probably make a hundred of puppies sad.

Items

• Mystical Skyfire Diamond now reduces the next spell cast by 20%, down from 50%. (It also might just be changed to straight stats, still in debate. Don't be surprised if this metagem just gets added stats with the current effect in the initial 2.4 notes, it's still being worked on.)
• Shaman Gladiator 4-set bonus now reduces pushback by 30%, down from 70%.

Well, if you're in Cat/Bear form, you'll get lots of extra healing now. I see that as a very big definite plus.

If these are real I thank blizzard for ending my addiction. My Resto shaman who has elemental as offspecc won't be fun to play anymore.

Yep, obvious fake. One look at the mage changes is enough to confirm that.

Thats proof right there its fake.   Turn undead doesn't work in pvp since players are humanoid and this spell only works on Undead and supposedly demons now.

Warlock pets. That said, I'm unsure if pet targeted spells, such as Hibernate, have reduced effect in PvP.

Wow... if people would try to fake anything, why not make it serious... I mean the mage changes are just a great laugh. If this DOES happend i will feel so owned  buts its just bullshit..

Yep, those are real.  Only Blizzard can continue the joke that is Lightwell.  It would be really really funny if it was not so sad.
