^^ I feel for you. I’ve been playing since the original beta.
Generally I think there are maybe some things that have been lost that added some flavour to the class. Totems, hands down, were iconic for shaman. They were removed (as I understand it) because they were a pain in pvp. Either they died to quickly or you ran out of range and had to re-cast them. But as a shaman? I felt naked without 4 totems slamming down around me. So I’d love to see those back as standard.
A lot of the rest of stuff though… Using your examples, did any warlock REALLY miss ritual of doom? Aside from the lols? Or curse of doom - so slow that you’d lose major dps if it didn’t tick properly on a boss kill (and useless on trash). Are paladins crying out for auras to come back? Really? I mean hey - maybe you are but I suspect there are other more interesting mechanics Blizz could think of to add spice to the specs. Not just ones that demand ‘buff plz’ then forgetting about it.
A. bunch of these things WERE removed for balance. Shaman complained in pvp about totems dying as mentioned. Auras, curses etc were removed to prevent people only bringing certain classes to things (which didn’t work out but hey…)
And other stuff seems to run the gamut between broken and useless. At one end you have Druids regaining Ursols Vortex and Cyclone - which effectively says ‘bring no other healer to mythic/pvp evahhhh’. On the other you have Mages getting non spec filler spells back. Which… okay? Maybe someone’s been crying out for a chance to cast fireball as a frost mage? Maybe when locked down? ish?
My main point isn’t that the classes don’t need fluff. They do. But just re-introducing old fluff isn’t really that much of a solution. (but hey - at least light well didn’t make a return)
