which talent is really needed for a tank knight?

[koetsu]

i was wondering.... ok the Iron Wall 5% perm dmg reduction is pretty fine. But Deliverance wroth it?

iron wall all the way if your full tank just my 2 cents do as you plz.add the iron wall to the tenacity =very hard to kill knight imo but if your wanting more attack id look at maybe swaping skills around to see what you like or adding double skill tree for pvp and battle grounds tank knights dont do alot of damage in bg or pvp so you will lose alot of fights ive noticed .

i have double skills, i ask this becouse i can't tank well Demon Temple boss
