How to properly use unbreakable will in sith raid and isolate ability

On the unbreakable will question it sounds like you watched an old video. In the past there was a lot more uncertainty on when the raid boss was going to annihilate. These day's as long as you are not suffering debuffs when he has a Drain Force coming up you generally can wait till it shows a zero count and you know it will be the next action. Now since your resistance team can do a lot of TM removal you might need to take a little care. But with a bit of practice you get a good feel for it.
