Long story short I would never improve by watching top Siegfried players play against other people. Would I try and use those tactics I watched and apply it to my own game? Sure. But it would fail me every time just because I didn't have the basic fundamentals down beforehand as well as those tactics feeling completely unnatural. Not to mention that those tactics would never work against other people at my level just because at scrub level any tactic works. What I'm trying to say is you need to become a good player beforehand to actually understand and apply what top players are doing.
You have to evolve as a player instead of jumping bridges that lead you nowhere. At least for me that's how it is. To me, becoming a better player is about playing thousands of games over and over again and mentally improving each game. How do good players get better if there's nobody above them? Its called repetition and the willingness to improve yourself on an individual level.
