I am not sure why people in this thread compare LB3 damage to their burst phase damage. You obviously wouldnt hit LB during your burst phase, you use it outside of one. Healer and Tank LBs are pretty useful in the right circumstances. The second flare&line stack on P2s is a great spot to tank LB to give more safety. Using it on the AoEs leading up to p4s phase 1 enrage is also some nice value and safety. DPS LB would be more damage but if accidents happen and people die to those aoes you are suddenly short on damage right before enrage. Healer LB is great on p3s life's agonies if you dont have an ast with you.
