Sorry, I'm not that helpful but I generally don't touch the LB unless I'm told to lol. I mainly run lv. 70 end game dungeons and raids though. It's not very often that we ever need to use LB. Most people have these dungeons and raids down pretty well. I haven't tried the sigmascape Savage yet so that could change things. Usually the tank or healer will say use LB after this or that phase or DPS LB now lol. Just too many dungeons for me to know which one is okay for me to use it and when I should save it for the tank or Healer. I just do what I'm told. The only exception to that is when things go really bad and the boss (usually the last boss) and he's only got a bit of health left then I'll hit it and try to avoid a wipe. Sorry, I've just never gotten that used to using LB or when and if I should use it. It all just depends on the dungeons and mechanics to tell the truth. I've seen Healers use it more frequently. I'm a bard so maybe that's why. I'm rarely called on to use it whereas I see them asking melee dps to hit it more often. I can only remmeber a couple of bosses where everyone wanted me to use it at a certain time.
