If you're not using RDM's LB3 to wipe the raid, are you even using RDM's LB3 right?

But no seriously, in most cases if a melee doesn't LB3 or if you have to hold it because your party is just that bad in regular content that you're most likely going to wipe without healer LB3, a RDM LB3 blinding the screen is the least of your worries.
