As a Tank, if a Melee DPS does not use LB on 2nd boss the moment it is charged and ready or when the bosses health is at 80%, I am gonna pop it. I am not going to make it collect dust while you can use LB and let it recharge before we get to the final boss.

If a Ranged DPS doesn't use their LB on W2W pulls then Imma pop it because clearly they aren't going to use it on a big group.

Also if LB2 is ready and the DPS does not use it immediately, at 10% HP Imma pop LB. DPS players need to learn it is not meant for your grand anime finishers where you pop it when the boss is at 5%-1% HP.
