Flash summoner spell is not the best summoner spell for everyone

Everyone thinks that Flash summoner spell is the best thing ever. Well, let me tell you right now that Flash is not the best summoner spell for everyone. Before everyone jumps on the attack, pay close attention to the evidence below.

I love watching pro players because they are amazing and they can do things us mortals cannot. That being said, if you pay close attention, even the pros sometimes misuse or make mistakes using Flash. Sometimes they flash away and still die, flash into a wall instead of past it, flash into an enemy attack or wrong direction, etc. Yes even the pros make mistakes, which is fine.

Now, take into consideration that the pros have amazing reflexes, prediction skills, and overall better decision-making than we mortals do. So now think about us mortals...we are bound to mess up Flash way more! If we suck compared to pros, then yes we are probably not using Flash nearly up to its full potential.

In conclusion, low elo players are probably better off not using Flash or using it far less often than the pros. There are many great summoner spells that are under-utilized. Please consider my explanation and analysis, then respond, thank you.
