I've seen several threads reference the combination of Div Shield & Div Sac as not working the way I thought it did. My understanding of this combo is that while Shielded, I can Div Sac and take 40% (specced) of all nearby raid member damage for the duration of the Shield since I never hit the 150% of my health limit.
Other users here have said it doesn't work this way. They say that even though the shield is up and I don't take damage, it still stops working after 150% of my health has been absorbed.
I've never seen any patch notes or blue threads that clearly state how this combination works. Can anyone demonstrate absolutely one way or the other? I don't think this ability is really worth the talent points if the absorb actually stops at 150% with shield up.
