Zul'aman - Timed chest rewards
3 drops have been re-added to the Zul'aman loot table, I already posted the two cloaks during the PTR days but as far as I know the legs are new, I guess it's worth a news. According to the first reports all these items drop from the 1st/2nd chest of the Zul'aman timed event.
Tanks and repair costs
I didn't see a lot of blue post about this in the past, Tharfor tries to explain the mechanics behind the repair/reagent costs for each class, and why it's not gonna change.
Hunters - Grimtotem Spirit Guide not tameable anymore
A few weeks ago Blizzard said that even if it wasn't intended in the first place, there wasn't any reason to remove the ability to tame Grimtotem Spirit Guides for hunters. Guess what ? They changed their mind, it's been hotfixed and they're not tameable anymore, however you'll be able to keep yours if you already tamed one.

We don't have any details on the 2.4 yet, but the class-balancing team is working on it.
