I find no use in the healer LB1 or 2, and have only seen them being used out of curiosity or boredom. That the bards can use the healer LB is a neat trick, but also one that almost never finds use aside from freak occurrences.

The LB 3 is better since it refreshes mana (and maybe TP, I honestly can't remember) with the resurrection, but it would be far more useful if it was done with a unique and less severe version of weakness or without weakness altogether. If SE decides to revamp the healer LP in HW I would shed no tears for the ones we have now. Unlike the DPS and tank LB (T13 lol), the healer LB seems to have no role in a well planned and executed encounter. And that's a damn shame.
