I don’t raid anymore on retail, but when I did I always went for the fotm ranged spec because it’s easier to follow boss mechanisms, my screen wasn’t overloaded with players and explosions, and in the end I had more uptime on boss fights. Plus with my old CPU it feels more fluid at range. Not dying was more important than raw DPS potential when doing mythic progress. And finally my guild had more ranged than melee slots open.
Now I’m a true casual and I enjoy SV a lot like I always did. But it’s true that I raided way more with ranged SV. It was fun and easy enough that you only needed muscle memory to do damage and could focus on boss fight.
