[blizzard]Dungeons and Raids

    * All 25- player raid bosses that drop set tokens will now drop and additional token!
    * Gems obtained through Heroic difficulty instances are no longer Unique-equipped.
    * Loot dropped by Doomlord Kazzak and Doomwalker has been changed to Bind on Equip. In addition, the cash dropped by these bosses has been significantly increased.
    * Scale of the Sands reputation will now be awarded in Hyjal at a much higher rate.

Professions

Enchanting
    * Added a recipe to convert a void crystal into two large prismatic shards.

Fishing
    * New Fishing Daily Quests! Visit the mysterious old man fishing at Silmyr Lake outside of Shattrath City to discover what treasures he has to offer.

Interface
 Along with Patch 2.4 we will be releasing a revamped in-game Interface Options screen. Most of the systems that interact with the current Interface Options screen have seen some code changes as a result. The new architecture for the system should allow AddOn authors to modify its contents without the taint issues presented by the current Interface Options system.

Additionally, this new system will contain an area for AddOn authors to present their own configuration options to players with a custom heading, subcategories, and frames. I'd like to encourage authors interested in utilizing these features to try the new system on the PTRs before Patch 2.4 is released. Basic details on how to use this system can be found in code comments in Blizzard_InterfaceUI.lua.

Please be aware that AddOns that interact with the Interface Options screen, modify it, or change the way that its options affect other systems within the game will need to be updated with the release of Patch 2.4

General
    * Characters will now retain talented spell ranks so when they retalent they do not have to relearn the spells from trainers.
    * Spell Haste: Spell haste now reduces the global cooldown on spells, down to a minimum of 1 second. This change does not apply to melee and ranged abilities.

Items
    * Players will now be able to purchase level 70 Superior quality PvP items from reputation vendors.
    * Items intended for Retribution Paladins have had their stats adjusted. Retribution Paladins should see an increase in dps as a result.
    * Players can now only carry 80 Conjured Manna Biscuits at a time.

Warlock
 Patch 2.4 will remove the restriction for Ritual of Summoning that prevents you from summoning players into instances. Provided the player meets the instance requirements, you'll be able to summon them in from anywhere in the world.

Well, not too much for now, but some of them (many, tbh) are really nice 

[Flippant]

The 'de' void crystals in to large prismatic shards sounds fun

Otherwise looks like another patch where a load of add-ons will cease to work, those that haven't been updated since the last patch - but still worked - are not going to work in the new one

[Annwyn]

Oooh, I love not having to retrain 7 ranks of CoH every time I've been playing around!

[Rowain]

Additional tier tokens, yay! At last maybe I can get the T4 helm

This one starts stacking haste. 1 sec life taps <3

Oh yeah, and quicker spell casts. Cool.

[Richàrd]

my advice to enchanters...

buy void crystals and sell your shards now

[Nolan78]

Row, didn't you get it during a Kara, some weeks ago? I rememeber a Karazhan in which you joined just before Prince...

*btw, if you want it I'm happy to help..just give a poke*

[Tomana]

Okey, looks like there will be new badge rewards in 2.4 as well 

Time to start some serious Kara/heroic farming as soon as we know more about that

[Rowain]

Row, didn't you get it during a Kara, some weeks ago?

That was on Row, on the 12th Prince kill of the smelly priest. 

Thy needs it alot more badly tho, feral itemization is crappy. While the pink hat is stylish, it is by far the weakest part of my tank gear.

[Kivarlyn]

row, don't be sad, I'm on 25 kills on prince with kiv and still no helm^
going to take arena one if don't drop neither this week >_>
