I wanted to see what would be BiS for me in 4.3. I run normal mode, and every BiS list I have seen in prior patches have all been heroic BiS lists. I do understand that the heroic gear is gonna be THE best in slot, but there are many of us that just run normal modes. This list is for them.
Disclaimer: I made a choice about trinkets based on what I have noticed while tanking in 4.2. So far, anything over 200k health when buffed is wasted. With that in mind, I have disreguarded the trinkets with Stamina on them in favor of trinkets that provide mitigation or avoidance. If you are not at 200k health when fully raid buffed, then you may want to choose one of the stamina trinkets instead.

There are heroic versions of all the items listed above. You will have to adjust your reforging accordingly. The reforging was targeted to give mastery to items that had none since mastery has no diminishing returns. Then, I tried to equal out dodge and parry. Since dodge and parry have the same diminishing returns, and they give the same amount of avoidance per point, you want to reforge out of the higher one and into the lower one. In this case, without reforging, I had more dodge than parry. I first reforged any hit and expertise into mastery. Then, I reforged dodge into mastery on gear that had no mastery. This allowed me to get my dodge and parry to within 30 points of rating of each other.
Also, the weapon and one of the trinkets come from the actual deathwing encounter. If may be a bit before you see those items drop in normal modes. If the 378 sword from spider boss in firelands is the best you have, then the LFR version of the 4.3 weapon is a nice upgrade. If you have the heroic sword from spider boss in firelands, then the LFR version of the new sword will not be a good upgrade. Wait for normal mode raid drop. Get whatever trinket that is an upgrade till the deathwing trinket drops. It will probably be a while before you see it.
