I honestly blame to top players for a lot of new players/average players laziness.
PP, Armada and HBox all play in a very set way, and doesn't use any of the newly developed and never implements something themselves (well I guess armada did some work before genesis 1 but not much if anything since then)
Mango also cannot do lots of the new stuff, and is a johning whiny ***** that encourages people to john and never "try" (unintended or not).
M2K is still stuck in 2009, and constantly complains about EVERYTHING. He also largely relies on self made gimmicks that **** players who don't know them but gets opened up by the top players, which is one of the reasons Marth players still cannot combo for **** (m2k's true comboing even on FD is actually bad) and most players learn flashy, gimmicky stuff instead of things that work all the time.
No top player uses Shield drops, option selects, powershield (barring a bit of armada), proper doubleshines etc...
Compare this to any other FGC/Esport where its the top players that constantly develop new technology, show it, make it the standard, not the mid level players who find something and then 4 years later people START looking into all the extremely useful stuff there is.
Smash players also suffer from low confidence etc, compared to the other games where people are both more mature and have more confidence. I'm tired of seeing people say "I wanna be as good as M2K at gimping/comboing" "I wanna be as aggressive as Mango" "I wanna be as consistent as armada" **** DAT ****
If you're gonna make it to their level, you gotta aim higher. People should be thinking "I wanna be the most consistent there is, but I wanna use all the high risk/high reward that Armada just doesn't wanna use" or "I wanna an aggressive playstyle just like Mango, but I'll be more consistent and have a better defense"
Of course, you can still watch them for inspiration and advice, but the problem is that most people aim to copy, not surpass
I'm obviously working hard to change this. I won't really be releasing tech until I've become (one of) the best though (everyone having twice my exp is a huge disadvantage, so I gotta do what I can)
EDIT: An important thing to add is that 95% of the playerbase of ANY GAME (and life)will not learn new tech unless they are handfed. Its not really until they are repetitively shown that one thing is good that they start to look into it and explore it (in esports this commonly happens when top players who everyone watches implements something new).
