Idea for a future Support Ultimate: "Shared Life"
This one comes from upcoming hero Alexstrasza in Heroes of the Storm. Here's a rough description of how it works:
#Shared Life Link with a target allied Champion. After a delay, the Champion with the lowest health percentage is set to the same HP% as the other Champion.
Picture this: Your teammate gets jumped by an assassin, so you use Shared Life on them. If they live long enough for it to kick in, your ally's health gets set to the same percentage as yours. Handy for perking up your ally and screwing up an enemy's single-target burst attempt, though not nearly as good if your team gets wombo-combo'd.
This could be really awesome on a future support Champion.
