Almost every complaint about the ShB job changes could be solved with talents

[Awful]

Look up Path of Exile too if you want a good example of "Unlimited Choices" but really only about 5 builds that work past a certain point.

I know this is off topic but that's extremely wrong, any build can work in PoE I played a Cast While Channeling/Volatile Dead/Scorching Ray Chieftain in Betrayal League on HC got to lvl 95 and died to Guardians before Uber Elder, a build can work it's the investment in PoE so that doesn't apply here at all and no one played Chieftain because it wasn't meta.

On topic no talents aren't gonna help with "choice" Legion and WoD started this trend with talents every milestone and the talents ranged from meta > passable > garbage, people are gonna go with the best talents and not bother with the garbage ones. I did Mythic+ mostly in Legion and BfA and you'd go with the best talents for Blood DK which is what I played, you'd hardly switch your talents out even despite the modifiers for the week because the talents you had were already so strong compared to the other ones.

Would I like more choice in XIV? Sure, but I don't like the illusion of choice if it was a concrete thing that if I could swap between outside of raids to benefit me for another raid then maybe I could see that it'd be engaging.
