Druids will likely use the first build in 5-mans and the second in raids. Resto druids no longer have genesis and nature's swiftness so they lost some burst healing capacity; however, they gained the ability to cast tranq on the move (artifact trait), which effectively removed one of their worst weaknesses. Tranq is now one of the best raid CDs in the game. They also bring a single target innervate (not to be confused with the former innervate), which lets a healer cast without a mana cost for 10 seconds. Finally, druids still have ironbark, albeit on a slightly longer cooldown.
Shamans: Resto shamans bring by far the most utility: two powerful raid cooldowns (healing tide and spirit link), a totem that is the equivalent of stampeding roar, and another totem that will automatically battle rez someone who is within its range. Shamans also regained ancestral vigor, a talent that adds a 10% health buff to the raid, which is likely to give them a de facto raid spot. Chain heal is not as affected by distance as others make it out to be. I never felt hopeless with a split raid; spirit link is the only spell that I found difficult to use in these situations. In 5-mans, I felt like I could use a tank healing CD, especially if I was in mythic+ dungeons with monk tanks (by far the weakest tanks in my opinion). Spirit link was not always reliable to save the tanks. Other than that, the spec was completely viable in both raids and 5-mans.
HPriests: Holy priests provide powerful burst healing via their new holy word spells, but they are on long cooldowns (1 minute each). In between those spells, I felt that the spec was somewhat bland. Renew is not as strong as it used to be, so priests have to time their other spells appropriately. Hymn is still a strong raid CD but not castable on the move, and guardian spirit is still excellent. Finally, H priests bring symbol of hope, a raid-wide innervate.
After playing a disc/holy priest for 11 years, I am main swapping for the first time. I have played all healers in mythic+10 dungeons on the beta, and resto druid is by far the most enjoyable for me. Our team will most likely be using two resto druids, a shaman, and a paladin for our core. We will have a shadow priest flex to healing if a fifth is needed.
