Shadow priest

Just asking to see if you could bring back the healing effect of shadow priest from dps. Like it used to be in classic. Self healing as well as heading towards party. Of course not making shadow priest a healer but just as a small assist. The former was a weak heal either way but it’s a cool effect to create damage as well as heal just as you have for disc spec. Maybe with more towards mana healing and some hp restoration. One of the things I miss from the old days of shadow priest. Thanks
