You’re getting a lot of differing opinions about talents and legendaries, so here’s another one.
Healing in keys is mostly about keeping your tank up and then throwing a few hots out to keep the others alive. If they’re making big mistakes, they’re likely to die. Our spot healing isn’t great, so there’s a finite amount of mistakes you can heal through.
To that end, certain playstyles are going to be better than others because of this caveat.
Dark Titan’s legendary (double lifebloom) is one of those ideas that looks great on paper, but doesn’t really fit the current mold. Keeping up two lifeblooms adds unnecessary globals that could be used elsewhere to make the run go smoother. You’re likely to want to use both lifeblooms during prides. However, photosynthesis is just not good enough to heal through prides on high keys. Flourish is.
With germination, you really need to be using the rejuv legendary. While you can probably have some measure of success with this build in m+, rejuv spam is not going to get the job done in m+ like it is more successful in raids.
What many top end resto druids use is the swiftmend legendary with C Ward, soul of the forest, and flourish.
Currently, tanks take an extraordinary amount of damage as compared to the end of BFA. In order to help them out, single target healing is at a premium. This is where C Ward comes into play. One of the previous comments shamed C Ward for only being active for 8 seconds. With this build, its uptime is hugely increased.
C Ward is our single best heal by leaps and bounds. If you follow the method described below, C Ward will likely be at or near the top of your healing done.
Once C Ward starts healing, you can swiftmend to add time to the hot (this affects other hots on the target as well). You can either swiftmend it again once the cd on swiftmend is available, or you can flourish if the timing lines up with needing to use flourish on a pride or a big pull. You can keep a C Ward hot ticking for about 35-40 seconds this way which means you can delay your next C Ward until that hot expires and repeat the process again with swiftmend.
This synergizes really well with soul of the forest as you can swiftmend the C Ward hot and then wild growth the party (if they’re taking damage) for the beginnings of a good aoe heal. If you’re in a pinch and everyone is getting hit hard (like the end of pride), swiftmend to extend the C Ward, wild growth, tranquility to 5 stacks and immediately flourish. If people are dying through that and spot heals after the flourish, then you’re either extremely undergeared (or they are) or they are taking huge amounts of unnecessary damage.
This playstyle is probably going to change once we no longer need to heal prides, but our mana efficiency is going to take a huge hurt, and tyrannical weeks are going to suck even more than they do already.
We shall see what the 9.1 meta is when it is figured out.
