i don't know about some ppl and i know how to tank to so the "your doing it wrong" is a waste of breath, i have sat and watched my skills while i was tanking, and one skill does nothing, which is Guard, i put that on my mate who was healer, had the Soresu form up, can't use guard if i don't, and had him wait till i was at half hp while i was tanking 2 mobs, and one heal he cast took all threat off me in one cast, so yeah, i'm thinking the Soresu form and guard are screwed some how, then there is the devirting part of the damage to you, he was getting attacked and my hp wasn't moving, and guard was up the entire time, so i think bioware needs to take a closer look at juggernaut tanking cause for me it doesn't appear to be working right.
