Existing content changes
Before any question, please read the Patch 3.0.2 FAQ on official forums

Once this patch is deployed, the following content will be disabled or removed :

The Atiesh quest-chain will not be completable anymore.
The Bear Mount from Zul'aman will no longer drop.
The Onyxia quest-chain has been removed from the game.
Naxxramas is "removed" from the game and moved to Dragonblight. (Unreachable until WotLK, obviously)
The ability to get titles related to Tier 4 or Tier 5 content is being removed. Of course, players who got them before the patch keep them. (Hand of A'dal, Champion of the Naaru)

Also, a few things are being changed or added :

Barbershops are now available in capital cities !
Achievements are being added to the game !
The amount of experience needed to level from 60 to 70 has been lowered.
New graphical effects are being added to the game, including the new shadow engine
The Stormwind Harbor will be available, but you won't be able to travel to Northrend until the release of WotLK. However it does have a working boat travelling between Auberdine and Stormwind.
The Caverns of Time have been slightly modified to add an entrance for CoT: Stratholme. The instance itself won't be available before WotLK, only the entrance is being added.
Mounts and Vanity Pets are now trainable spells and the old items will be used to teach you these spells. Once a mount or pet is learned you can access it through the Character Panel.
Various tokens like Badges of Justice or Honor Points are all merged in the new Token Interface. It will also remove the Badges of Justice and PvP Tokens from your bags to free up even more space !
The in-game Calendar used to schedule raids or events between your friends and guildmate will be available by typing /calendar

Item changes

+Healing and +Spell damage stats are being merged into a single +Spell power stat. Healers' talents and spells have been updated accordingly to compensate this change.
Items with magic school-specific damage like +shadow or +nature have been converted to +spell power as well. This include most of the TBC items except for some enchantments like Sunfire or Soulfrost.
Protection Paladin and Tanking Warrior sets to reflect changes on the new mechanics. A lot of non set items are also being changed. See this post.

Raid changes

Raids buffs, debuffs, and auras stacking have been revamped, please check this post for more information and our raid composition simulation tool to see how it works now.
All TBC raid monsters will have their health reduced by about 30%. (see this post)
The standard melee damage output will be reduced as well.
Boss abilities remain unchanged, except for Illidan who won't use Shear anymore.

This is obviusly the biggest bunch of changes since TBC, and maybe even since implementation. Gameplay is going to be changing for everyone. Many class mechanics have been entirely revamped. Speaking of that lets get to the Shaman changes

Well those havent been updated in weeks on the offical ptr site and the patch notes dont have them

So lets get to inscriptions
