Wait, what happened here?

So I have been getting some drops out of 10 man Ulduar lately and they appear at first glance to be nice upgrades for bear. However, while my attack power, haste, crit, and dodge go up, my health goes down. I have gotten the Valorous Nightsong head and shoulder pieces. And it kills me that it actually lowered my health approximately 2000 over what I was currently wearing. (I think I switched out my hands too, but since I can't seem to remember what the drop was that I switched the T7.5 hands for, ...)

So now the question becomes, should I sacrifice health for the other stats? Now, understand the following, I am not an enchanter, or a blacksmith, or a jewelcrafter so I don't have a huge health pool to start with. I only have about 32.5K unbuffed these days so when I switched those couple of pieces out and dropped below 30K, I nearly had a heart attack. I am not happy with my health pool being at 32.5K to start with, let alone falling below that. However, I do have about 42% dodge and 40% crit with around 6ooo AP.

But still, if your armor, dodge, AP, crit and haste all went up, would you sacrifice health?
