shorasgemmtheres too many cases where you wanna press crouch at a different time to pressing jump1. Ctap
e.g. ctaps, crouching before jumping to gain extra height
2. Demoman jumping
Too many.
Crouch jump script is good 'cause you usually jump a lot in this game. Why would you be bothered pressing 2 keys instead of 1 so many times?
3. pressing crouch before jump to gain extra height
4. the times you dont crouch when jumping so you don't get knocked back to ozfortress by a scout or something
that's plenty of reasons for me not to use one
