Whoa… just realized I have not posted in a while…
So, I have been playing very little as of late.
I did log on to do the first 2 phases of Pre Cata Content. A bunch of quests, and the feat of strength. You can get good information on the feat from this Tripping the Rifts.
A bit of FYI, you can get the achievement by gaining the buff in Azeroth. You can only loot the item for the daily if you do it at level content. I recommend doing it old world personally.
I stocked up on mats to get a jump start on leveling professions. I personally have to level tailoring, enchanting, jewelcrafting, inscription, and alchemy. After doing some WOWhead research I found only enchanting allows for stocking old mats to level and it is only a guaranteed 10 points.
News came out from a dev that the current beta pace of leveling will persist in Cataclysm release. What this means is that leveling to 85 is going to be VERY fast. Be prepared to jump in 5 man heroics and crafting epics quickly in order to gear up for raiding.
I believe the new Feral DPS rule of thumb is going to continue to be Mastery>Agility>Haste> and going for the Hit and Expertise caps where possible. I see a lot of Strength gear floating around with lots of mastery on it, I am guessing that will be desirable as well.
Cataclysm definitely looks like it is going to be a lot of fun. I plan on jumping right in and I have already purchased the digital download.
Another notable is that in a 10 player raid, only 1 battle rez can be used per attempt. This will impact my 10 man right off the bat as we had 1 lock and 2 druids. Yes, Soulstone counts as a battle rez. After the rez counter hits 1, meaning someone actually accepted an in battle rez, trying another will net you an error that the spell is not available.
