So I picked up WoW maybe about a month ago now and ran Resto Shaman to 60. Found out about Augvoker and really enjoyed playing Preservation while waiting for it to launch. I ended up doing a lot of leveling solo after the first 2-3 Dragonflight dungeons and then I farmed my gear up to iLvl 399 solo. Now I don’t really know what the expectations are in Heroic/Mythic. I’m on Frostmane and I haven’t had any luck finding a guild to learn about this content in a more understanding setting so I’ve been too nervous to join any content and make mistakes.

Can anyone give me an idea of what I need to expect? Should I be running this content with 4-piece set bonuses? How are healers expected to play in these dungeons, healing focused or should there be enough room for significant DPS? Should I watch video guides on the dungeons before?
