Allow Godmode for everyone and the problem is solved.
Is that hard for you to detect too? xd
Jokes aside,I think sprinthook or whatever other mod similar to it should be forbidden.
Maybe it cannot be easily detected in short duels,but if you can notice someone sprinting for a long time,ban at once.
Maybe we should have a movement speed counter or something for each player individually.We would know from test play how fast walking and running would be normally,and know approximately for how long someone can maintain the maximum speed until they run out of stamina.
Yeah,that doesn't help with the "tapping or not tapping the spacebar" problem,but it could help with other connected issues.
