Well, H pally is the healer most nerfed in BfA and the consequences are in this article. The feeling of slow and weak need to be fixed soon. The spec is incomplete right now. I don't know why Blizz decide to delete a healer of the competitive map (m+, raid and pvp wise)
As long as IK is in charge things won't improve, going retri because holy can't cut it has no appeal. Releasing BfA on a set date rather than when things are ready will have a toll...
All the healers lost flavor with the artifact removal. They have to recreate a base spec that is working before building on that. The specs got nerfed so hard in the legion prepatch, only to give it back with the artifact. After removing it now, they had to re tune every skill and cooldown. All in all Paladin came out pretty lucky, compared to holy priest, shaman and even druid. Thanks to beacon, Paladin will always have a guaranteed raidspot and it's utility and beacon of virtue will keep it to stay top dog in m+.
