1. Can PvE mobs/boss kill the Lightspring?
I was in LFR tonight. There were a couple of cases where the Lightspring was gone, but my Lightspring spell was still on CD. I thought this would happen when its 15 charges were used up.
It was strange because I was in a really good group, that I was trying to find somebody to heal. I thought maybe I missed some big hits, but when I checked Recount, only 6 ticks of Lightspring Renew. So, the Lightspring was not used up when it disappeared.
Since these happened during Horridon and Council, and both fights had sand traps. I wonder if sand traps that spawn underneath the Lightspring would have killed it. Could that be possible?
2. The tooltip says, "...Attacks done to you equal to 30% of your total health will cancel the effect..."
In a heavy aoe damage phase, raid members are likely to be lower than 50% and healed by Lightspring. But it is also easy for me to get hit for 30% of my health within a short time. Does this mean in such a situation, Lightspring Renew would most likely not last the full duration?
