I was wondering when jumping around double satcheling should I still be holding W in mid air while strafing? (I am used to CS GO Straftring where you cannot touch W) and should I be crouching?

Sry but I had to point it out like every second game my team gets a player named 'I miss her' usualy playing jett. I just want to ask who do the players miss and where did this all start?

Like if you're defending or if you want to catch an enemy lurking, how do you hold an angle so that you can kill enemies easier? ( I also have trouble with off angles as well )
