Tip for safest way to deal with Dreadnode + Brainjack combo ?

[Alise]

Our tank stands as far in The Avatar's hitbox as possible, grabs hate on the Dreadnaught. Once the Dreadnaught is at him, he takes a few steps back as to pull the Dreadnaught further up so it won't cleave the Brainjack target, then moves back in while keeping the Dreadnaught facing away from the group. It takes some practice but once you have it down it shouldn't be an issue with the positioning.

If doing it that way, when brainjack happen. Dreadnod will flip over to attack the person on pair with tank. (since the tank will move closer to the center from the start point which you said to be far from boss)

No, not always. It all depends on how much the Tank is moved when Brain Jack goes out.
Orophin sounds like he does it very much like I myself do ( or my Tank does )

Tank moves IN the HIT Box of Avatar ( almost to center ) to grab the Dread. Once aggro is set, he will take a few steps backwards, to move Dread closer to Avatar, then back IN on the Hit Box to limit his movement when Brain Jack happens.
This, is about all a Tank can do, the rest of it is on the person assisting the Brain Jack. In my case, a dps ( me )
If the dps is too far back, he will move the Tank, flipping the Avatar and/or Dread.
