Cataclysm Companion Pets Preview
I finally have enough data from the beta to post a decent preview of companion pets introduced in the expansion! This might not be the final list but it's much more impressive than the first one I posted a few weeks ago, I think we had 3 pets back then. And well, you could always visit Warcraftpets, Breanni is nice.
Achievements Rewards
A couple of achievements will reward you with new pets, most of them are Guild Achievements unlocking the ability to purchase these pets for gold in the guild reward panel, assuming you have enough reputation with your guild.




Professions
Professions get a fair amount of pets in this expansion, if your plan is to get absolutely all the pet you will probably have to learn and drop a couple of professions.








Quest Rewards
A couple of pets are rewarded through quests, including the super awesome Sunflower.




Others
If a pet cannot fit in one of the category above, it's most likely here!


Real Life Events
Two pets are tied to real life events, you probably already know about them.




Unknown
The drop locations of these pets is still unknown.

Landro's Lil XT

We are also talking a lot about just buffing tank threat across the board, because we've heard a lot recently that it's still too twitchy. (Source)
Tanking classes cannot AE Tank anymore
That actually isn't an intended change. We don't want AE healing to be trivial. I'll use some examples:
A) Pile of 20 whelps. Go ahead and AE tank this and ask your dps to AE too. You probably don't even need Shield Slam.
B) One giant. I wouldn't use Thunder Clap at all on this, except as needed to keep the debuff up. We want Thunder Clap to be terrible for holding single targets. (I don't think many tanks would argue this point.)
C) A pack of 4 targets that you plan to burn down one at a time. Here is the biggest point of contention. Thunder Clap should be fine for establishing initial aggro (though Shockwave will be better), and it should be fine for keeping add #3 off of the healer. But you should feel like you have to go to town with single target abilities on add #1 that the dps are all focused on. Then you should switch attention to add #2. In Lich King, it was too easy to just hold this whole group with Thunder Clap spam, and to be fair, the dps would just AE as well.
D) The same pack as in C, but this time you decide to CC add #3 and #4. In this case, you should be able to live fine without Thunder Clap at all (unless you really need the debuff). (Source)
[...] Right. If you are trying to AE tank and a bad dps is attacking the wrong target and dies, we call that justice. If you are trying to AE tank and a healer pulls aggo, then threat generation is just too low and we need to buff it. (Source)

Cannot macro Lifebloom while in Tree of Life on Beta
This is a (dumb) limitation of our macro system, where it gets confused if you have two spells with the same name. In this case, the Tree of Life Lifebloom is actually a different spell than normal Lifebloom. The macro tries to cast (normal) Lifebloom, sees that you can't because it isn't allowed in Tree of Life, and just bails. Lifebloom is not the only spell in this category.
We understand why this is bad and are working on a fix. (Source)
