Just want to chime in, yeah if your screaming for lb3 chances are your good dps realized you really need dps to finish the fight so they are planning it around CDs, aoes, mechanics, and rotation. Asking for lb3 multiple times also puts pressure on them to do it. Some people need to chill with the multiple lb3 calls. A perfectly placed lb when you actually need dps can take a bit of time sometimes, having people repeatedly tell you to do it, or have a ranged/caster do it a split second before you because they think you won't is pretty frustrating.
