ok i just hit 70 this last weekend (undead warrior-Burningdemon(for the horde!) and even though i don't like tanking, im going 2 go prot for my guild. (also so i can in groups so EASY)

But i now for a fact my armor is not good for tanking, so where and what should i do 2 get tanking gear good enough for Kara?

any help would be great!

Shatered halls, Botanica, Arcantraz, Mechanar, BM, Shadow labyrinth...

I can make a complete list with nice gear if you want but I think you got it, I gues you have Carthgrapher or Atlas so look for your gear on that.

491 defense skill (although the min is 490 the character screen rounds up) minimum.
12000 HP and you should be ok to start KZ / heroics, HP should ping up to around 14000 when you get hold of some kara gear. New badge loot is awesome too.
