Correct. Its a different skillset that requires problem solving, critical thinking, and pattern recognition skills (beyond just feeling like something is off). Many discussions I've had with the skillful players in MB2 often get blindsided by emotions, because they're venting frustrations. Which often makes it hard to drill things down to the core/root of the issue.
Personally, I think based on probably about a decade of having balance discussions with Sev, I think he is one of the ones that often falls into the pitfall of having design opinions that mostly benefit his style of play which can be at the detriment of others. And I also think his characterization of Tempest not listening to him for saber stuff is wildly out of place. I witnessed Tempest listening to him and discussing things with him a lot. Now as things got closer to release he may not have, which is true based on what I saw, but that is because in my opinion Sev has been an unreliable source for gameplay feedback, and because Sev didn't attend test sessions when Tempest specifically asked for saber testers in the beta channel.
You're literally talking to someone, who isn't a mechanic, but learned how to disassemble, restore, and reassemble a car in a home garage. One that is my daily driver. I figure out shit on my own. Often you can't tell if someone is unqualified until you know/test them multiple times. There are many people who are licensed plumbers or "master mechanics" who don't know shit. I've had master mechanics who have been doing things for 40 years tell me something on my car that was flat out wrong, and when I challenged them on it they got all offended. Yet, I fixed the issue myself for thousands cheaper than they wanted to do it, and I've driven 4,000 miles even through harsh winter on things I installed myself and my car is performing better than any time a professional mechanic has seen it in the last 10 years.
