The game is what it is. They implemented a real time strike system without anticipating the extremes people would take it to.
By not changing it while having every opportunity to, and by stating that drags were intended, they legitimized the techniques.
You can dislike them, but they’re within the limits imposed by the game, there’s no trickery or glitches required to do them, accessible to everyone etc.
If the combatants were aliens, people would care less. Unfortunately, people can’t suspend belief long enough to realize it’s a dumb sword fighting game that doesn’t take itself seriously or claim to be realistic in any way. And at this point, the only way for it to be changed is if someone made a mod.
