Recently I read somewhere this piece of advice. (Not only that, but I have even read that start playing stuff like the English if you are a novice can hurt your chess learning process because of a lack of "the fundamentals")
The two main reason behind this piece of advice should be:
1. Open games tend to lead to tactical games
2. e4 e5 is the fundamentals/basics of pawn structures, and more complex form can be really understood if you got the basics. The optimal learning order should be something like this: open games, closed, semi-open, semi-closed or indians, and hyper-modern stuff
And this is WHAT I DON'T UNDERSTAND:
1. got it, beginners need first of all improve tactics, but don't you get tactics in every game?
2. Why double king's pawn structures are the basics? Why something like the English is considered to be more complex and difficult to understand?
