None of this has anything to do with what you could get from talents back then. For obvious reasons(seeing as the intended design was for them to be mostly the same for all 3 specs).
The only comparison worth making is between the core specs themselves.
This is kind of the whole point isn’t it?
People are so focused on what they were back then. And many are happy to judge their individual elements based on modern design philosophies. Philosophies that are irrelevant to the time before Legion.
The whole point is that it doesn’t matter whether RSV, as it was back then, would not hold up today. The whole point is that RSV if taken into the more modern era and with more distinguishing elements and functionality being added, it would be perfectly fine. Even with modern standards.
You tell me @Vitwolfen, if you compare modern MM to what can be seen in the linked post below, can you honestly say that they would be too similar to not warrant being separate spec options for the class?
