Sword forms were invented to address the needs of the 16th Century not the 21st.
Your modern urban opponent carries a baseball bat, knife, screwdriver or gun. Not a sword.
You will not be carrying a sword either.
Swords were once the favoured combat weapon.
The martial arts which grew around swordplay were a necessary and relevant area of study.
The sword skills were literally a matter of life and death.
Not any more.
