My point was that a lot of stuff is gone, as you already said as well. I didn't want to argue about specific spells... Earth Shield is more or less still available in PvE, the same goes with the individual heals.
For me, i rolled priest in WoD and stuck with it. During Legion almost no change in playstyle for Holy, some minor changes for Disc. That is what bothered me with my shaman. Blizzard usually changes Shamans around a lot even during an Addon, so you have to adapt after every minor or major patch to the likings of Blizzard. And ofc current Shaman are no where near Classic/BC Shaman so i am kinda falling into the nostalgic love for shamans past and cannot identify with it anymore nowadays.
