In theory, being able to drop HTT and then continue with normal healing should be very powerful. In practice it's not, because you have to be running flat out to compete with other mass raid healing spells, and that's hard on mana. For a Druid or a Holy Priest, using their mass heal is also a break on their mana consumption. It used to be for us as well, but now it simply isn't. Also, the other mass heals have doubled power outside of raids, making them useful in 5-mans. HTT does not.
Ankh totem and +10% health are on the same row, and earthen wall totem is considered better.
As for not topping HPS meters - if the raid is stacked, why shouldn't Shamans top meters in progression where health will often spike low and Shaman mastery should shine? If Shamans can't top meters early in a raid with lots of stacking, they'll never top meters, and stacked raids on low health is where Shamans are supposed to be at their best. Shamans losing healing spots as raids go on farm is annoying, but understandable. Shamans not being welcome when they should be the go-to healer means they'll be benched permanently.
Right now, Resto Shamans are the least popular healer by log numbers for m+ (looking at warcraftlogs.com), and only Holy Priests underperform them (and they can go Disc and become as gods). Overall, in mythic raiding they are the least popular healer, though numbers are fairly even (making Priests about twice as popular as any other class), however, when you look at parse numbers on each individual boss only on MOTHER are Shamans popular healers, and only on MOTHER and Vectis does their throughput not suck.
Utility does not cover for this, especially as Shamans lack a tank cooldown, lack a unique/semi-unique raid buff, and other healers have utility as well. Heck, even Priests do, given how useful Mass Dispel can be these days. It is nice that Hex is somewhat useful these days, but if the healer is the one having to CC adds, your RL might need to be having a chat with their DPS.
In previous expansions, terrible spread healing (often still better than today, mind), was somewhat compensated for by amazing stacked healing, especially with the many CDs Shamans had. Now the stacked healing is lacking, and Shamans don't have the CDs either.
