"Saves" stat for supports
How many times a teammate is bout to die and you save them with heals/ shields/ swallowing whole/ etc., but adds nothing to your overall score? Saves should = assist in terms of gold and kda.
Currently the reward is "ty raka" or "nj Tahm" and maybe an honor at the end of the match. But if a dude's about to die and your heal gets him/her/it away alive - this is a major play - saves a death, takes a k from the other team. Now if this happens multiple times in a match, that could really add up in terms of gold/ kda.
Maybe not even it on your kda - but if you're tracking CC score, may as well track saves, right?
I know, saving teammates is your job as a support. It'd be like if you gave Zed a K for every time he... gets a kill I guess?
