BfA has a new UI layout, what else, I don't know, if they don't want you to use Addons in Alpha, even if we don't know the reasons, ...
... then you don't use them?
A novel thought, but maybe worth thinking about it.
Also alarming: The claimed dependency on healing addons. Are they too good, mandatory, whatever! I only heal with my Shaman and Paladin this is really easymode, and at least personally think Priest healing is rather challenging. I think this isn't something addons should solve, it's up to Blizzard to solve that.
