First time tanking .. need some advice

[Fath]

Thanks.

If you checked out my armory .. what would u say i should get next ? trinket ? gloves? back? or save for helm?
I doubt i am ever gonna down the lich king .. ive only done up rot and fester and downed them both
im trying to get into a guild that strictly does 10 mans instead of always pugging

the trinket will give me like 100 point gs boost lol .. and also put me close to 41k unbuffed health
