I find it weird the reason number one on why people use their LB is because "it's pretty", and not because your DPS job can get the best damage /effect out of it depending on the situation.

Single target, melee LB.
Multi targets, Caster or Ranged depending on how the mobs are placed.

If you DPS complain you never get to use your LB, think about healers and Tanks. Since the launch of the game, ive probably used my healer LB ( 1, 2 and 3 ) like 15-20 times top and probably not even 10 times on my Tanks.
