And yet if anyone of those players decided to pick up more tech skill they would become even better. All technical skill does is add iterations and new scenarios to your attack. I hate it when people bring up the aniki example. Aniki has technical skill, he essentially does everything an advanced link/samus player should do with exception to wavedashing, which is easily compensated for by simply shorthopping backwards and throwing a boomer/bomb/missle.
Here is an example: I'm able to beat people with lots of technical skill using one hand because I will play smarter. However, people who I'm on roughly the same skill plane as me I would probably not be able to beat with one hand because my technical abilities greatly diminish with one hand. In the end, you win at Smash because you were SMARTER than the other opponant. However, at the higher levels, where everyone is smart, you NEED the technical skill in place simply to keep up with the other player.
The 2002/2003 era was notorious for not really having technical skill. The technical gap in that time frame between a relative newby and a competitive player was really not very pronounced and especially not as pronounced as it is today. Things have changed though, and just about any competitive player can just whip out Falco and shl/pillar/combo a casual player with relative ease.
My Fox is very technical, the only thing it lacks is the short hop double laser out of the shine, but for all intents and purposes my fox loses to people that my Pichu can beat. Why? I'm not smart with fox, I use the same entry over and over and I don't abuse his kill moves (usmash/uair/fsmash), instead, I try to go for shine combo's that really serve no purpose. This doesn't say that mindgames will always beat technical skill. PC Chris would be no match for KoreanDJ if he couldn't wavedash out of a shine or walltech, those technical aspects of Fox/Falco are so important that without them he would simply not be able to keep up with someone else of his caliber of thinking. The problem with your examples Wak is that you aren't comparing two likes. You are essentially comparing two players who aren't of equal skill or experiance, because in the end "mindgames" and "technical skill" aren't competing. Technical skill simply adds dimensions to a players game, which as the game progresses reveals that the characters with the most (in quantity and quality) iterations/fakes/approaches/mix ups will be the characters that dominate the game because smart players will use these things and integrate them into their game. My fox has one approach, so it gets destroyed by anyone who can learn from their mistakes. Now Falco on the other hand has at least a half dozen or dozen approaches, and my Doc/Peach has even more than that. You can liken it to football, where most coaches will never repeat the same play twice because once one play happens they assume the defense will read it next time. Could an NFL team dominate a college team simply using one play? Yes, but that isn't comparing two likes (just as me saying that I can beat randomscrub309 who can waveshine with fox and is technically sound but has never been to a tournament is also not comparing two likes).
