Hi. I have always played as mage until i got tired of getting one or two-shot dead. Decided to make a paladin tank.

I have now tanked almost the entire naxx with no problem at all, all the heroics 5man dungeons which now feel more like normal and tried a few days ago tanking Toc10 which i thought surprisingly easy.

Apart from that i've tanked as off-tank Ulduar and Toc10 and i think i've done good.

Had almost 5k gs, with 33k~ hp unbuffed and capped defense, but i have dropped a bit because i just finally got The Black Heart: http://www.wowhead.com/item=47216 .
I would like to know if i should use it or the previous one http://www.wowhead.com/item=47243 Mark of the Relentless.

I think i still need to get the HoR normal shield and the boots from FoS hc. After this i want to know as i am geared now what should i be tanking and what should i be after next because i'm sort of lost since i have nothing else to get from emblems of triumph and it's really hard getting 2 frosts a day.
