Paladin Lay on Hands bugged?

[Grimstrike]

This is not the first time I have had this happen to me on Blue. I am not sure if this is the correct bug section (this feels like more of a class skill instead of a healing spell), but either way this instant heal seems bugged. I finally have the screenshot of the chat window where it shows that I should have been healed, but instead I was hit and died. Thank you for taking a look, your time is appreciated
