So this is a question for moonkins who have completed the Protectors of the Endless encounter in Terrace of the Endless Spring. Our first few attempts on this we were hitting the enrage timer and I was trying to figure out why when our DPS is pretty solid. I then was watching our moonkin and noticed that he was multi-dotting all 3 bosses for no reason (since they heal up when one dies and all). We then stated multiple times to our raiders that they need to be focusing down the targets one at a time (skull). He continued to multi-dot. When I approached him directly in a tell I asked him why he's still wasting GCDs to multi-dot the other targets. He claimed that when he dots the others while one of his CDs is up that it increases the damage of his dots - effectively doing more damage to our main target.
Now I personally have not played boomkin since mid Cata, but after doing some research after the raid, I could not find any information that supported what he told me. Could someone please enlighten me on how multi-dotting the other two bosses (who will later heal up) could possibly increase the damage he's doing to our main target?
As far as I could tell, he was meter padding.
