Never been a an of Stewie yet I don't believe in the normies way of making team better : "-x +y".
Liquid would improve with better tactics indeed. But don't forget that liquid is not as tacticless as people think. They were one of the top 3 team in antistrating their opponent with ENCE during their prime.
Also yes, when I wrote my previous comment I was thinking "I dont name him so I'm underrating NAF". NAF problem is : despite being consistant, he is not one of the best in his category : snipers. Unlike, for exemple, Elige is as rifler, or Twist is as an anchor.
