Out of Shadow, Elemental, Enhancement, Boomkin, Feral, Retribution, and Windwalker?
Both in terms of how well they do when they stop DPSing and offheal in an emergency, and who can provide support/force multiplication while DPSing (such as Resto Affinity’s passive smartheal).
you’re not supposed to offheal. Ever. It’s too weak and eats your dps.
Want to dps and heal - play disc priest
I’d be interested in Disc if they got a Gladiator Stance. Or got reverted to MoP Disc.
The one version of disc I really loved. MoP disc.
Predicting that incoming raid damage and prepping the raid with an enormous spirit shell. It was awesome.
Ret, Moonkin and Feral all have some decent in combat healing. Windwalker is alright as energy regens back fairly quick.
It isn’t worth it to toss out a heal on a dps shaman. Better off dropping earth elemental to soak damage instead.
And I don’t know for shadow as I’ve disliked that spec since vanilla. But bubbles probably help I’d feel.
Discipline Priest.
Beast Mastery Hunter with spirit beast pet
Vampiric Embrace is a very strong smart heal for shadow, however their “off heal” is garbage and only slightly helpful for out of combat healing.
Feral still gets free heals after using combo points, right? Haven’t played one in a long time. If so, they get my vote.
this is easily Druid with Heart of the Wild
Probably boomkin with resto affinity, as you even get to passively heal the team if your health is full, and you get a few healing abilities
Resto druid with feral affinity and all feral talents actually wrecks every 3 mins.
Disc Priest is the only true hybrid that plays heals and dps at the same time.
Otherwise, sounds like you want to play Druid-Shaman-Monk-Paladin, something that can self-heal on the side.
If you’re looking for utility, Shaman may honestly be a good choice because you have totems.
From my limited experience, Enh Shaman feels like a hybrid healer/dps class. You have your base heals(chain heal, healing surge), Earth Shield (If talented) and Healing Stream Totem.
The heals might not be incredible, but they do help out.
Ret. Word of Glory, BoP, HoF, LoH, Selfless Healer, etc allow you to be a full on support DPS. Good ret play is really impactful, and they have a lot of tools to mitigate bad situations for themselves and their group.
Only if you’re terrible at the game. All healers should be using their damage abilities. Holy Paladin and Mistweaver Monk get healing throughput for using theirs.
Well, I meant that you could take a break from spot healing and through attonement, all your damage becomes HoTs basically.
Although I do agree that many healers don’t seem to dps at all, probably too busy looking at the health bars instead of helping the fights go faster.
I didn’t know it was baked into the other specs as it was for disc, not since they removed fistweaving.
Yeah, Crusader’s Might gives you CDR for Holy Shock when you Crusader Strike, Crusader Strike at baseline gives Holy Power, Judgement does a metric ton of damage, Hammer is fantastic as a HP generator and also does a bunch of damage. Pal can generate a lot of resources by DPSing. Speccing into Glimmer and Avenging Crusader means you can basically play Holy as a melee DPS spec. You’re healing your group with every attack you make with Avenging Crusader up, and Glimmer lets you use Shock offensively while providing healing, or defensively while doing damage. Holy Prism is the same deal as Glimmer, use it to heal and you get decent AoE damage, use it for damage and you get a decent AoE heal.
Paladin is just as DPS centric as Disc. hPal only starts hardcasting when things are going wrong.
Pretty sure Fistweaving is still more or less in the game, but its viability is dubious depending on the patch. I dont play monk, and the only healer I play is Paladin, so it’s not exactly my expertise, but I’ve seen some good MW players pump.
If you truly want that old school MMO dps/healing hybrid feel, Disc priest or a Resto Druid catweaving is the only way. Maaaybe a Resto shaman flinging elemental spells. WoW just doesn’t have that level of flexibility these days. 
WoG was nerfed from the BFA heal everyone loved. It’s crap with SL mechanics.
Selfless healer is “ok” at best but you can’t sit their and off heal in an emergency.
The best class for that is something with a full mana pool I.e. priest.
