The problem with fighting games is that they're stuck in an evolutionist dead end.
1. They can't move BACK, because none would accept to question the fundamentals (2D movement, hit points, attacks & grabs as the entire repertoire)
2. And they can't move FORWARD, because they've already hit a wall with what they're allowed to use. All these hyper-specialized techs are just variants on top of the same old.
But there is a surprising revelation behind all this, if you read between the lines of 1+2. The meaning of fighting games being stuck in an eternal limbo of Street Fighter 2 clones, TO BE RECOGNIZED AS FIGHTING GAMES, is not that any evolution is impossible but rather that any divergent games would be labeled a different genre.
MOBAs and ASSFAGGOTS for instance, could be seen as an evolution of fighting games. They share the exact same sport-like spirit: a tag team match between varied, but balanced alternatives. The entirety of presentation and controls is different, to achieve the same result.
Not convinced, frightened by the weird words bad? Imagine having a fight between two classes, like Demo and Soldier; then port the same battle in a fighting game: the spirit would be the same, but you would have to translate all the movements and tactical arrangements into a set of distinct moves, way harder to master and learn because they're less apparent and less natural to execute. In a word: more archaic.
