But i said for me short doesnt give more complete pass. I played with short 4 games and results accordingly 79 82 82 79(with short lol)
maybe your midfield players were in a bad day, or maybe oppo was playing high pressing or maybe this % would be lower if use long pass or maybe the combination with counters wasn't successful.

short+normal/attack without counters?
yes, if I feel superior

when do you use def+mix
when oppo is equal or stronger , or when I want to keep a result , or when I have a good result and I feel that oppo (even weaker) will go with attack
