I used mine once about a year ago as well. Didnt really need it I just wanted to see myself do it finally, lol. No one said anything either so w/e. Honestly the only LB's I have ever seen with any significant frequency is the DPS ones. Ive used the tank one once during Garuda (which saved our asses and lead to a win finally) but never seen it otherwise and healers ive seen a handful of times when group is doing poorly.

Does the healer LB work better with actual healers or is it the same across all classes that can use it?
