Take this advice, it's quite good. I would have wrote this the other day, but I was too lazy. But seriously, take this advice.Except your missing out on many simple fundamental ideas.
I honestly feel that you need to take a step back so to speak, and try to rethink a lot of this. A lot of your ideas seem to stem from your personal experiences, then dictating that on a wide range of situations. There is nothing wrong with finding things out for yourself, and in a lot of cases it can give you a deeper understanding of a situation. But you need to realize that your personal experience is a very narrow way to learn. We already know that FFAs will never be "deep", you need to study the broad range of others to see some things.
You seem to be a nice dude, but you're stuck in this weird scrubish mentality. You need to broaden your views and really question your logic before you post. A lot of things you questioned had no line of reasoning to it at all. Make sure to look at each side as objectively as possible before putting your opinions down. Otherwise you make yourself look like a complete fool.
Also I think I read earlier that you only played competitive smash for 6 months. If that's true, you haven't even scratched the surface of competitive smash.
You also questioned why should we play smash competitively when the skills do not transfer over.
-First of all, it's more fun than playing casually (opinion).
-Second of all, smash has elements in a fighting game that transfers over to other fighting games primarily spacing, zoning, and mingames to a certain extent (fact).
-For an application to life, smash (or any fast paced strategy game) has you constantly analyze the situation at hand, forces you to look at all your options, and then make the best decisions that you can. Analyzing the situation and making a decision is something you do all the time in your life. Granted the situation are vastly different, but it's still a skill that transfer over. (fact)
I also believe you stated that competitive smash is just memorization of a series of buttons.
WRONG WRONG WRONG WRONG
Please do not spout such nonsense. While knowing the ins and outs of your moves and how to execute them are a key element to any competitve game, you're once again forgetting the control aspect of the game as MajinSweet pointed out.
Also are you telling me when you play casually, all you do is button mash? Because even in casual play, you have to remember a series of button presses.
Anyways, that was just my two cents. Felt like I needed to get that off my chest.
