This is pretty much it. Although, I know the goal was that the Cata Talents would create multiple viable playstyles within a spec while being newbie-firendly: The problem being that was very rarely the case. Notably the builds we saw during BFA with Mistweavers & holy paladins.
All-in-all there were overall more viable builds during the Talent Tree era so we might as well go back to that.
RIP Cataclysm Era Talents - You were an exciting new system that never paid off that somehow lasted 10 years
It looks like that exact playstyle will exist in Frost: A dps build revolving around Rime & Chill Streak, spreading dots while managing resources.
