Eh, this stuff happens. Using the LB is always a judgment call and while it's easy for anyone to type "lb" it is not so easy for a dps to type:
"After careful analysis of the situation, I believe that the LB would best be used for this purpose and at this time. Of course, I would hate to unilaterally decide this for the entire party, so I shall await unanimous agreement on this matter before pulling the trigger."
...That would be absurd.
