I just have 2 LB bindings... 1 binding all 5 LB spam, 2nd binding all LB spam cept the main who has /cast [target=focustargettarget] lesser healing wave. I use it in heroics for healing earth elementals as needed and for just general healing. 5x lesser healing wave is 0 dps and lots of overhealing, so I'll spam 2 lesser healing waves and 8 lightning bolts instead off 2 casts
