Ah now i understand. In your first comment i quoted you talked about large scale reworks.
Completely agree. They could give us the second DoT back in 6.5. Not much change in play but a welcome one.
In fact i would give all healers a second DoT (maybe with lower potency but longer time) and a AOE DoT that shares a timer with one of the other DoTs for trash. Reuse old symbols and animations and voila.
