I think that melee players on the whole perpetuate fundamental errors of understanding that create massive stumbling blocks in both conceptualizing and gameplay.
* Option vs Option as overly important (false: where/when trumps what every time)
* Neutral is a valuable concept (false: Position is a valuable concept)
* Fundamentals exist (false: fundamentals are useless generalizations)
* Methodology of first things first (false: the end is important, the means is the means. Combo trees that don't end with a stock can be uprooted.)
Specific and verifiable information is the most valuable. Generalizations are at best misleading and at worst actively harmful. Identifying and solving for specific problems is the only alternative to "learning through osmosis."
