Question about the next chapter

onemind

Ok so I have 3 questions and just looking for an awnser

1 why change coupe de gra (cant spell it) you can only use it 5 times a game

2 will the movement speed of pounce be enough to hit a surivor that runs around a small rock?

3 45s before you get punnished for haveing Victor in 45s 2 or 3 gens could be half done
