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?

I see quite a few people put him after either Astra or Kayo but how much can his abilities do? “You have the ability to rift-walk and you stay here? What a shame, there are so many better worlds out there..." - Viper voiceline. Does this...
