Hpala has been good (top 2/3 healer) for basically the entire of BFA.
MW has been the best healer in BFA twice - first it was nerfed after erm a month or so and this time, well its hard to know yet if the nerf was enough but seems its probably still the best.
If you’re focusing on 2s though, depends what your friend plays
Pala is very cd based healer i was overhelmed at first there are many cds you have to trade properly. Mw in other hand is easy af. Only thing you should practice is this channel canceling stuff which is not hard( if its still a thing )
Gonna keep it short and simple for you. If you were in a car crash, and tragically had brain damage, you’d succeed far and beyond currently has MW Monk in PvP and PvE over Holy Paladin.
Holy paladin is extremely CD based, and if you mess up, or come across the wrong comp, you might as well afk.
If you’re mainly going to play with destro/dh in 2s. I’d say resto druid. Offensive playstyle with feral affinity is a ton of fun. Every healer is viable. Sure MW is easier rating but it’s boring af. Druid is weaker but really fun. Paladin might be a good balance in between the two.
