Id like to thank you guys for your opinions and advice and help! Thank you very much!

So I enjoy my sith assassin but tanking does not work out. Then I read all these post about how they can't tank because they are nerfed now. But I still want to tank. So what stats should I stack now or what should I focus on mainly so I at least dont die 6 times each instance. Basically if yer a good Assassin tank tell me what you do. Thx. Ive been playing wow for years so I know how it sucks when they nerf something good but ive only been playing this game for a few months so I dont know what the "old" assassin tanks were like.

Thx u have both answered my question. I totally understand now!

Do the items you get from the cartel market packs are they like boa gear in wow. So the top I have doesnt have a min level requirement so will the stats go up as I go up in level as well. Sorry this is so vague but the other items I have seen have a min level requirement. So basically if a item doesnt have that will it get better as u get better..Thats my question.
