That is honestly hilarious from a old, old used to play Tekken player.
There’s a Smash Bros mechanic called Stale Moves where repeating the same move many times causes it to deal less damage. It feels like a worthwhile topic to delve on for more interesting fights, but given the way knockback works there could be a better target than just damage adjustment.
It highlights the crucial flaw with Tekken for me: you have to just memorize how to defend everything your opponents can do to you rather than being able to intuit it on the fly. Which moves hit high/medium/low/overhead or track horizontally? There’s no language to it; it’s just done on a per move basis for balancing reasons, which means it would take me forever to get to the part where I actually get to think and play the game. This string, mashing 3, has highs, mediums, and lows all built in, plus it low profiles some counter attacks from opponents. This bot would beat me, too.
